The Manifest Destiny was a phrase coined in 1845. It expressed the spirit and meaning that United States was destined by God and by its history, to expand its dominion and spread democracy and capitalism across the entire North American continent so as to get as much land as possible. As a result, millions of Americans began to migrate westward in search of new lands as well as opportunities.
After the Soviet Union lost twenty million soldiers in WW2, Stalin wanted to make buffer zones around friendly states so they would never be invaded again.
