World War III, often called the Hot War or the Great War, lasted 7 hours of the day of October 27, 1962. The war began largely as the result of the extreme rivalry between the United States and Soviet Union. When the United States discovers Soviet missiles in the nearby nation of Cuba, President John F. Kennedy commands an invasion of the country. Cuba responds with nuclear attack, which sparks a worldwide nuclear war, destroying much of the world. Every nation in the world as it was known was eventually destroyed as a result of the war.
World War II Edit
Wikipedia article: 
On September 1, 1939, German forces under Adolf Hitler invaded Poland. This dramatically increased tensions with the United States and Soviet Union to Germany, and caused Great Britain, France, and other countries to declare war on Germany. Earlier that year, the Nazis and Soviets signed a "non-aggression pact". On September 17, 1939, Soviet forces invaded Poland as well. Germany and Russia outlined their zones of occupation in Poland that day. On May 10, 1940 Germany triumphed over France. On June 22, 1941, Nazi Germany launched an invasion against Soviet Russia and the countries went to war.
Through the 1930s, the Empire of Japan, an ally of Germany, conquered swaths of China and other parts of Asia. The United States stopped selling oil to Japan for this, and the Japanese launched an attack on Pearl Harbor, a U.S. naval base in Honolulu, Hawaii, on December 7, 1941 in response. The United States ceased their neutrality in the war, and President Franklin D. Roosevelt and Congress declared war on Japan, as well as Germany.
France was swiftly liberated from Nazi occupation in an Allied campaign which lasted from August 19-25, 1944.
During the war a new weapon of mass destruction was invented; the atomic bomb. The United States, with support from Great Britain, dropped two of these bombs on Japanese cities Hiroshima and Nagasaki on August 6 and 9 of 1945. Also on August 9, the Soviet Union invaded the Japanese puppet state of Manchukuo in northern China. Meanwhile, in Europe, the Allies are pushing through Germany. On April 16, 1945, the Battle of Berlin began. Adolf Hitler committed suicide on April 30. The battle ended on May 2, 1945. The war officially ended September 2, 1945.
The United States and Soviet Union come out of the war as the two major world superpowers. The Allies began to rebuild Europe. Germany was split into West and East Germany as two spheres of influence. The East was influenced by the Soviet ideals of communism, and the West was influenced by the United States ideals of freedom and democracy. Eastern Europe fell into the Soviet sphere of influence (Eastern Bloc), and rejected the U.S. rebuild plan called the Marshall Plan. Western Europe was called the Western Bloc, influenced by the U.S. Alliances between the Blocs and countries throughout the world shifted constantly.
Cold War Edit
The exact date/year the Cold War started is debated amongst historians, but many agree it started after the Denazification process of Europe (the process of removing Nazi influence from Europe) ended, and the Western and Eastern Blocs were created. The "war" was a political rivalry between the United States and Soviet Union. These countries both ended up with atomic weapons like the ones dropped on Japan, both sides constantly making improvements to the weapon and racing to build an arsenal larger than the other.
The Cold War was called the Cold War because it was mainly a war in which the countries fought indirectly, and were afraid of fighting each other directly because their nuclear weapons could destroy the world.
Before World War II, beginning on August 1, 1927, the Republic of China faced a communist rebellion. Both sides agreed to cease fighting until the Empire of Japan could be stopped from taking over the country (December 22, 1936). On March 31, 1946, the war continued until the communist victory official on May 1, 1950. The new "People's Republic of China" was founded and joined the Soviet-led communist Eastern Bloc.
The Korean Peninsula had been controlled by the Empire of Japan from 1910 until the end of World War II. After WWII, the Peninsula was divided into two spheres of influence, much like Europe, with two countries divided by the 38th Parallel. North Korea supported the Eastern Bloc and South Korea supported the Western Bloc. On June 25, 1950, North Korean forces crossed the 38th Parallel and invaded the South. This was the start of the Korean War, and the U.S. (backed by the United Nations which was founded after World War II) intervened. The Soviet Union and China gave direct support to the North. The war ended on July 22, 1953, in a military stalemate and no border changes.
On August 13, 1961, the Berlin Wall was built so that the border between East and West Germany was made more clear. Many Germans on both sides of the wall try to defy the wall, and are killed.
Fulgencio Batista was elected to be the President of the Caribbean island nation of Cuba in 1940, and remained in office until 1944. After his term ended, Batista moved to Florida, only to come back and run for president again in 1952. When his defeat was seemingly certain, he staged a military coup and took power again. Once a man preaching liberty and freedom, Batista began revoking many political liberties from the people of Cuba, including the right to strike. Batista grew more and more oppressive over time.
Fidel Castro and the Cuban Revolution Edit
Many Cubans were fed up with Batista's rule. This included Fidel Castro, who organized a rebellion and attacked the Moncado Barracks in Santiago on July 26, 1953. The attack was an absolute failure, however, and many of the rebels were killed. Fidel Castro and his brother Raúl called for a cease fire, and Fidel went to trial, where he gave his defense speech and was sentenced to 15 years in prison. All rebels who were imprisoned were released by Fulgencio Batista himself under political pressure. Fidel and Raúl and some other rebels relocated to Mexico.
The Castro brothers met with other exiles in Mexico to plot the overthrow of Batista. Fidel received training from Alberto Bayo, a Cuban military leader who assisted the Republicans in the Spanish Civil War (1936 - 1939). Argentine revolutionary Ernesto "Che" Guevara also decided to help the Castro brothers in the overthrow of Batista. Some people believed the rebels were Communists, which Castro denied.
The rebels returned to Cuba and started to take over, town by town. Castro's army finally reached the Cuban capital, Havana, where people exited their homes cheering the overthrow of Batista's government on January 1, 1959. Batista fled Cuba to the Dominican Republic, and sought refuge in several countries, including the United States and Mexico, both of which denied him entry. Finally dictator of Portugal, António Salazar allowed him to stay in the country as long as he never be involved in politics there.
Fidel Castro turned out to be a communist and seeked a Cuban alliance with the Eastern Bloc and the Soviet Union.
Bay of Pigs Invasion Edit
On April 17, 1961, the CIA of the United States conducted a mission in Cuba to overthrow and kill Fidel Castro. The mission ended a failure on April 19.
The Cuban Missile Crisis Edit
On October 14, 1962, American spy planes discovered Soviet missiles in Cuba. The next day, the CIA reviews the photographs and the U.S. Department of State is notified. On October 16, President John F. Kennedy is notified of the situation. On October 25, a naval blockade was set up to stop Soviet warheads from being sent to Cuba, but the blockade failed.
On October 26, Kennedy informs the Executive Committee of the National Security Council (EXCOMM) that he believes an invasion of Cuba is the only solution for the situation. The Armed Forces are prepared for invasion of Cuba, as well as the possibility of the use of nuclear weapons.
The Hot War Edit
On October 27, 1962, the United States invades Cuba. Cuba immediately responds with nuclear attack against the United States. Soon, the rest of the world hears of the situation, and countries of the Western and Eastern Blocs go to war, and with heavy use of nuclear weapons.
The war lasted no more than 7 hours. Nearly every country is destroyed that day, and eventually countries that didn't participate in the war also collapsed.
