The Beginning of the Cold War: Superpowers, Nuclear Fear, and a Divided Europe

While the wreckage of World War II had not yet been cleared, two new giants were rising on the world stage: the United States and the Soviet Union. The emergence of these two nations as superpowers marked the beginning of that long and tense era known as the “Cold War.” (This historic term was first used in 1947 by the American economist and statesman Bernard Baruch).

The primary critical developments that shaped international politics and the fate of the world during this new era were:

The Collapse of Europe: The fact that Europe and its established states, which had been the centre of the traditional balance of power and politics for centuries, emerged from the war with massive devastation, practically in ruins.

The New Superpowers: The filling of this massive political vacuum by the USA and the Soviet Union, who emerged from the war victorious and much stronger, claiming the status of “superpowers.”

The Shadow of Nuclear Weapons: Undoubtedly, the most defining element of this era was the development of nuclear weapons. This terrifying invention continues to directly shape both era and modern international crises. Just as we see today in the ongoing tensions between the US and Iran or in modern warfare strategies, nuclear deterrence is the greatest diplomatic weapon inherited from the Cold War.

With Europe withdrawing from the stage of world politics after World War II, the international order took on a sharply bipolar nature centred around the USA and the Soviet Union. One of the first concrete steps of this polarization was the secret bargain that went down in history as the Percentages Agreement, which took place in Moscow in October 1944. Aimed at definitively establishing spheres of influence in Eastern Europe, this agreement saw British Prime Minister Churchill and Soviet Leader Stalin determine their dominance over Eastern European countries by dividing them into percentages on a simple scrap of paper.

According to this, the fate of entire nations was divided by these ruthless ratios:

·         Romania: 90% USSR, 10% UK

·         Greece: 90% UK (with the US), 10% USSR

·         Yugoslavia: 50% USSR, 50% UK

·         Hungary: 50% USSR, 50% UK (Soviet ratio was later increased)

·         Bulgaria: 75% USSR, 25% UK (Soviet ratio was later increased)

The Berlin Crisis and the Baruch Plan

The first major and volatile crisis of the Cold War erupted in the heart of Germany, the country that suffered the heaviest wounds of the war. Following World War II, just like the rest of Germany, the capital city of Berlin was divided into four occupation zones by the victorious powers (the US, UK, France, and the USSR). However, the Soviet Union’s aggressive attempt to push Western powers completely out of its occupation zone and its deliberate prevention of German reunification severed all ties. When a compromise proved impossible, the US, UK, and France made a swift move to merge their respective occupation zones, laying the foundations for West Germany (and West Berlin). This situation triggered the historic “Berlin Crisis,” bringing the world to the brink of a new war.

In response to the Soviet Union’s ruthless 1948 Berlin Blockade, which cut off all land and rail routes to force Western powers out of the city, the US and UK launched the Berlin Airlift, one of the most legendary maneuvers of the Cold War. Wanting to save the city without triggering a hot conflict, Allied planes performed an unprecedented logistical miracle by flying day and night for nearly a year to airdrop thousands of tons of food, coal, and medical supplies into West Berlin. Faced with the West's unwavering resolve, the Soviets were forced to lift the blockade in May 1949, and this humanitarian operation went down in memory as one of the greatest psychological victories of the free world against communism.

Nuclear Crisis

The US submitted a proposal to the UN known as the “Baruch Plan” for the control of the atomic bomb, a weapon it had used at the end of WWII to prove its ultimate power to the world. This plan envisioned the creation of an international authority with unlimited inspection powers over nations to monitor the development and use of atomic energy. The US even demanded an alteration of the famous “veto” system in the UN Security Council to ensure that violators of the agreement could not block their own punishment.

However, the Soviet Union categorically rejected this plan. The Stalin administration harboured a highly justified fear: if this plan were implemented, the US would remain the sole “monopoly” capable of manufacturing nuclear weapons, and America, which already heavily dominated the UN, would completely manipulate this newly established atomic commission for its own interests. This mistrust between the US, which was unwilling to share its nuclear secrets, and the Soviets, who rejected this inspection plan, pushed the tension between the two superpowers to its peak, officially igniting the terrifying global nuclear arms race.

The Construction of the Eastern Bloc and the First Cracks

As Europe was divided in two, the fate of the countries behind the “Iron Curtain” had already been sealed. Thanks to the power vacuum created by the war and the military presence of the Red Army, Marxist-Leninist parties rapidly seized political power in countries like Hungary, Romania, and Bulgaria. The greatest share in the establishment of communist regimes in these countries undoubtedly belonged to Soviet tanks.

However, not all of the Eastern Bloc was under the absolute control of the Soviets. Two countries stepped outside this rule and drew their own destinies: Yugoslavia and Albania.

·        Yugoslavia: Not owing its power to Soviet armies and having driven out the Nazis with its own strong partisan resistance, Yugoslavia (under the leadership of Tito) exhibited an independent communist movement from the very beginning and refused to fall into the Soviet orbit.

·       Albania: Similarly, the National Liberation Front led by Enver Hoxha seized power by its own strength on November 29, 1944. Initially allied with the Soviets, Albania eventually opposed this hegemony and completely broke away from the Soviet Union in 1961.

The other Eastern European countries, apart from these two exceptions, faced direct Soviet intervention (such as tanks rolling into the streets) at the slightest attempt at independence.

Up to this point, we have talked about what the concept of the Cold War means, the general characteristics of the era, the post-war devastation, and how that famous bipolar world (US-USSR) was separated by sharp lines. In other words, we have made quite a “hot” and solid entry into that tense and long Cold War era!

Now, we are moving on to the First Phase of this massive period (1947-1950s). But don't worry; without getting bogged down in details and endless diplomatic crises, we will continue on our way by briefly touching only upon those most critical turning points that changed the fate of the world.

From Casablanca to Potsdam: The Conferences That Shaped the Post-War (part ıv)

As millions of soldiers fought on the front lines, the true fate of the world was being determined at those tense diplomatic tables stretching from Casablanca to Yalta and from Tehran to Potsdam. If you are ready, we are stepping behind the scenes of those historic conferences where the seeds of peace (and the ensuing silent Cold War) were sown.

Casablanca Conference, January 14-24, 1943.

Casablanca Conference (January 1943)

The leaders of the US and Britain announced to the world that the war would only end with the “unconditional surrender” of Germany, Italy, and Japan. This uncompromising decision would later be criticized for prolonging the war. It was also decided to attack Italy (Sicily) to relieve pressure on the Soviets and to make preparations to draw Turkey into the war.

Washington and Quebec Conferences (May - August 1943)

The location of the second front was a massive point of contention. Although British Prime Minister Churchill insisted on opening the front in the Balkans via Turkey, the US successfully pushed for the front to be opened on the Normandy coast of France.

Tehran Conference (November 1943)

The “Big Three” (Roosevelt, Churchill, Stalin) met for the first time. The date for the Normandy Landings (May 1944) was finalized, and the necessity of a global organization to maintain post-war peace was approved at the highest level for the first time.

Moscow and Cairo Conferences (October - November 1943)

In Moscow, the trial of war criminals (the foundation of the Nuremberg Trials) was decided, while in Cairo, the fate of the Far East, the expulsion of Japan from its colonies, and the independence of Korea were discussed.

Second Moscow Conference (October 1944)

One of the darkest bargains of the war took place here. Churchill and Stalin practically divided the Balkans into percentages on a piece of paper (e.g., Romania and Bulgaria were largely left to Soviet influence, while Greece was conceded to the British sphere).

Yalta Conference (February 1945)

It was decided to divide Germany into four occupation zones and to jointly administer Berlin. A condition was set for the soon-to-be-established United Nations (UN): those who declared war on the Axis powers by March 1, 1945, would become founding members. Following this strategic decision, Turkey symbolically declared war on Germany and Japan just shortly before the war ended.

San Francisco Conference (June 1945)

The United Nations was officially founded with the participation of 51 nations, including Turkey. The most critical decision was granting permanent “veto power” in the UN Security Council to the US, Britain, the USSR, China, and France.

Potsdam Conference (July - August 1945)

This was the final major gathering of the Allies. The focus was not on how to end the war, but on how to manage the peace. The complete eradication of Nazi institutions, the trial of war criminals, and the demilitarization of Germany were finalized.

Paris Peace Treaties (February 1947)

Symbolizing the legal end of the war, this series of treaties redrew the borders of the defeated nations (Italy, Hungary, Bulgaria, Romania, Finland). Under this framework, Italy was forced to cede Kastellorizo (Meis) and the Dodecanese Islands to Greece.

But what was the ultimate toll of this six-year nightmare that forced humanity to pay the heaviest price it had ever seen? In the next stage of our series, we will examine the political, economic, and social consequences World War II left behind; and take a closer look at the United Nations, founded to protect global peace, along with its specialized agencies that continue to shape today’s world.

From Normandy to Hiroshima: The Allied Victory and the End of World War II (part III)

From Pearl Harbour to Normandy, from the deserts of North Africa to the ruins of Berlin, the final act of the Second World War was a relentless Allied advance that left no corner of the Axis empire untouched. Without losing momentum, we continue where we left off, for while Europe lay in ruins, the war in the Pacific was far from over.

US Entry into the War: The Atlantic Charter

The day after the Pearl Harbour attack, on December 8, 1941, the US officially entered the war. America, which had initially remained neutral and only provided military supplies to Britain through the "Lend-Lease Act," was now on the battlefield with its entire industrial might.

However, just before the US physically entered the war, on August 14, 1941, British Prime Minister Churchill and US President Roosevelt published the Atlantic Charter, which would change the course of history. This charter promised that no territories would be gained after the war, that nations would determine their own destinies (self-determination), freedom of trade on the high seas, and total disarmament. The Atlantic Charter was the first and strongest foundation of the United Nations (UN) organization that would be established after the war.

The Fall of North Africa and Italy

As the tide of the war began to turn in favour of the Allies, the first major counter-offensive against the German war machine took place in North Africa. A massive force of 100,000 British and US troops, commanded by General Dwight D. Eisenhower, made a successful landing on the coasts of Morocco and Algeria. Although strong German reinforcements brought in via the Mediterranean by air and sea put up a fierce resistance in Tunisia, the Axis forces were completely crushed in North Africa by May 1943 after gruelling battles.

Without losing momentum, the Allies attacked what they saw as the “soft underbelly of Europe”, Italy (via Sicily), in July 1943. This heavy blow and relentless bombing brought an end to the fascist dictator Benito Mussolini. With Italy’s unconditional surrender in September and the capture of its fleet at Malta, the Germans were forced to enter the peninsula to protect their southern borders and defend their former ally's territory, bringing them face-to-face with the Allies.

The Liberation of Europe: The Historic Normandy Landings

Following North Africa and Italy, preparations began for a “Second Front” of unprecedented scale to completely liberate Europe from Nazi occupation. In May 1944, a massive armada of 4,000 ships and landing craft was prepared for the US, British, and Canadian troops gathered in southern England. While the Germans, deceived by false intelligence, expected the attack to come from the Strait of Dover (Calais), the Supreme Commander of the Allied forces, General Eisenhower, gave the historic order: The target was the Normandy coast, located between Cherbourg and Le Havre.

On the morning of June 6, 1944 (D-Day), the largest amphibious operation in history began, involving paratroopers, heavy bombers, and thousands of soldiers. Shattering the German defence lines and driving relentlessly west across Northern France, the Allies liberated Paris on August 25, 1944, tearing the Nazi shadow away from France.

The Fall of the Third Reich and the Surrender of Germany

Following the liberation of France and the Allied advance in Italy (the capture of Florence in August 1944 and the breaching of the Pisa-Rimini defence line), Germany was literally trapped.

By April 1945, as Allied armies crossed the Po River and advanced toward the Alps, Soviet armies simultaneously encircled Berlin from the east. Adolf Hitler, the man who set the whole world on fire, committed suicide in his bunker in his ruined capital, leaving his position to Admiral Karl Doenitz. Shortly after, with the official fall of Berlin on May 2, 1945, Germany hoisted the white flag, and the bloody war that had left Europe in ruins finally came to an end on the continent.

When the Sun Went Dark: Hiroshima and Nagasaki

On the morning of August 6, 1945, at exactly 8:15 AM, an American bomber named “Enola Gay” dropped the first atomic bomb, dubbed “Little Boy,” over the skies of Hiroshima. Within seconds, 60% of the city was wiped off the map. While 140,000 people lost their lives initially, this number reached 230,000 in the following years due to the invisible and deadly effects of radiation.

While the world was still reeling from this shock, just three days later, on August 9, 1945, at 12:02 PM, Nagasaki was targeted. A plutonium bomb named “Fat Man,” possessing the power of a massive 21 kilotons of TNT, instantly turned 75,000 people to ashes. Over the next five years, just as many people died in agony from radiation poisoning or were left permanently disabled.

Japan had no strength left to resist. With Japan’s unconditional surrender on September 2, 1945, World War II, which had cost millions of lives, redrawn borders, and left the world in ruins, officially and definitively came to an end.

World War II had ended, but the world it left behind was unrecognisable. Now came the harder question: what next? In our next chapter, we look at the conferences that tried to answer it and the fragile peace they attempted to build.
