African Americans were allowed to fight for the allies and gained recognition as well as respect for how well they excelled on the battlefield. They found that things remained the same when they returned home.

The Cold war was a global conflict that was fought between the United States and a capitalist democratic thought against the Soviet Union, with it's ideals of socialism.
It was brought about due to the growing conflict in the post-World War II era when only two super powers remained on earth.
Both countries wanted to exert global influence and since both had Nuclear Weapons, there were very few chances of direct conflict.
Hence, the war was fought trough proxies around the world. If a government was allied with one party, the other country would fund opposition rebels to overthrow the government.
This was played out extensively in Korea, Vietnam and Cambodia, where US funded and Soviet funded militias fought bloody battles. In all these countries, Communist rebels had become extremely powerful.

By 1900, 38% of the world's wealth was held by the United States. By 1914, the US produced as much coal as Britain and Germany combined, as well as producing over 40% of the world's iron.
But before World War I, the United States tended to take an isolationist stance toward other nations. World War I advanced the US into superpower status as a nation that used its industrial might to involve itself in global affairs.
