World War II: From Economic Crisis to Global Conflict

The Interwar Period and the Road to War

After World War I, the United States imposed the Dawes Plan on Germany. This was a series of economic measures involving loans aimed at increasing the value of the German mark during the Roaring Twenties. However, several factors led to renewed conflict:

• Nationalist Discontent: Italy and Germany were dissatisfied with the post-war order.
• The Treaty of Versailles: This treaty obligated territorial changes, which later influenced the conquest of Poland and Czechoslovakia.
• Diplomatic Tensions: Italy was discontented with the Triple Entente regarding promised territories like Abyssinia.
• Economic Protectionism: During the Great Depression, European governments adopted protectionist policies to reduce imports.
• Expansionism: Germany, Italy, and Japan sought to expand their territories to secure raw materials.
• Appeasement: Policies adopted by England toward Italy and Germany tolerated their initial territorial expansions.

Major Military Campaigns and Turning Points

In 1939, Hitler invaded Poland, situated between Germany and the USSR. By 1940, the Führer invaded Denmark, Norway, the Netherlands, Belgium, Luxembourg, and Paris using Luftwaffe attacks. During this time, the UK fought three major battles: the Battle of Britain, the Battle of the Atlantic, and campaigns within Germany.

In 1941, Hitler launched Operation Barbarossa against the USSR. Simultaneously, Japan launched a surprise attack on Pearl Harbor, prompting the USA to enter the war. Germany and Italy invaded Greece and Yugoslavia, while Hungary, Romania, Slovakia, and Bulgaria joined the Axis Powers (Berlin-Rome-Tokyo), which appeared invincible at the time.

The Allied Counter-Offensive

The tide turned in 1942 when the USA defeated Japan at the Battle of Midway and the UK defeated Germany in Africa. In 1943, the USSR achieved a decisive victory in Stalingrad. The Allies then invaded the Mediterranean and defeated Italy. By 1944, the USA landed in Normandy. In 1945, the USA and UK attacked from the west while the USSR attacked from the east, leading to Hitler's suicide in April. Finally, in August, President Truman ordered the use of atomic bombs on Hiroshima and Nagasaki, leading to Japan's surrender.

The Legacy of the Second World War

In conclusion, approximately 55 million people died during this period. Radical political extremes took power, and traditional powers like France and the UK lost their international standing. The USA and the USSR emerged as the new global superpowers; these two countries would remain in a Cold War for nearly 50 years.
