War and Civil Conflict 1900 to Present - AP World History: Modern

The "domino theory" refers to the belief that if one country adopts communism (or "falls" to it), then its neighboring countries will "fall" too. It was used to justify intervening in the fight between Communist North Vietnam and non-Communist South Vietnam.

Kaiser Wilhelm II was the last German emperor, and was deposed in 1918 after a 30 year reign.

Mutually Assured Destruction refers to the prevalent philosophy during the Cold War that if either the USSR or the USA launched a nuclear attack, the other could retaliate with sufficient speed and power that both would be destroyed. This kept the Cold War from erupting into nuclear conflict.

During World War I, huge losses were incurred by combatants when they sent unarmored soldiers against machine guns.

The Russian Revolution was bloody, but grew out of World War I.

The Chinese Civil War was bloody, but by that time military planners already knew how to deal tactically with machine-guns.

By the time of the Battle of Midway, war planners already knew the effectiveness and danger of machine-guns.

By the time of the Persian Gulf war, war planners were using global positioning systems (GPS) and air strikes, machine-guns were already well understood.

The Chinese Civil War lasted almost half a century, in the middle of which the Japanese invaded.

After the Japanese invasion, many factions within the Chinese civil war joined forces against the invaders, but fighting resumed once the Japanese had been defeated.

Although the Japanese invasion certainly changed the dynamic of China's Civil War, the war began before the Japanese invasion.

Some factions within the Chinese Civil War were anti-communist, while others were supported by Moscow and pro-communist.

When Archduke Franz-Ferdinand of the Austria-Hungary Empire visited the Bosnian capital of Sarajevo, he was assassinated by Serbian nationalist Gavrillo Princip. As a result, Germany aligned with Austria-Hungary against Serbia (and it's major ally Russia), and soon nations were taking sides and war broke out. This assassination was the spark that ignited the growing nationalist and militaristic tendencies that had been growing throughout the end of the 19th century.

Advances in technology led to a completely new style of warfare that came with the turn of the 20th century. While hand to hand combat fell out of style, armies would dig trenches to protect their front lines, which they would defend with Machine guns and heavy artillery. The result were vast stretches of "no man's land" between trenches that were virtually deserted for fear of being gunned down. These mass killing technologies led to significantly higher death rates.

WWI brought the concept of Total War to new heights, in this global war the conflict stretched far beyond the military. Factories were re-purposed for the war effort, propaganda was spread, and food was rationed. In many nations conscription was established to recruit more actively for the armed forces.

The Treaty of Versailles placed almost total blame for WWI on Germany and imposed major punishments on them including: stripping them of domestic and oversees territories, limiting the size of the military, imposing harsh economic sanctions. Resentment born from this treaty would eventually cause Hitler's rise to power and World War II.

D-Day was the military for what became the famous invasion of Normandy, France, by the Allied Powers to attempt to begin the liberation of Europe from Nazi Germany. V-Day refers to Victory Day, or the day the Axis powers surrendered to the Allied powers.

The United States created the Marshall Plan after World War II, as an economic strategy to help European countries be less vulnerable to the Soviet attempts to invade them after World War II.

General MacArthur initially evacuated the Philippines upon Japanese invasion during War World II on the Pacific front. He promised them he would return later in the war to deliver them from the Japanese -and he did, regaining the territory from the Japanese in 1944.

Americans contributed to the war effort in many ways; however, the internet was not available at this time so emails could not be sent to soldiers.

It was not until the bombing of Pearl Harbor by the Japanese on December 7th, 1941 that the United States officially joined World War II. The Allied powers war with Germany begin in late 1939.

Italy was led by Mussolini during World War II.

General De Gaulle was the leader of the French Resistance during World War II. He was in charge of a secret radio program through which he communicated with the Resistance. He also assisted in the organization and carrying out of the invasion of Normandy, now known as D-Day.

All of the mentioned answers were seen during World War One, except for the use of nuclear weapons, which were developed later.

It was the bombing of Hiroshima and Nagasaki that, debatably, led to or hastened the conclusion of World War II on the Pacific front.

Rosie the Riveter symbolized the American female spirit as many women began working at traditionally male-run jobs such as work in the factories.
