If your history teachers hated America, they may not have told you of the Baruch Plan of June, 1946. As the only superpower with a then monopoly atomic weapons, the United States offered to destroy our atomic bombs and place ours and others' fissionable materials under control of the United Nations. Russia rejected the plan. Exploded their first atomic bomb in 1949.
Beginning in 1948, Russia blocked all land routes into Berlin where American, French , and Brits controlled parts of Berlin. The problem is that Berlin was well behind the post-war area occupied by Russian soldiers. They reasoned the West Berliners would starve, and the United States give in and turn Berlin over to complete Russian control.
Instead the United States began flying food and coal into West Berlin to feed and comfort the Germans. At its height planes were landing at Templehof Airport every 30 seconds, offloading quickly, and flying out again.
It's best portrayed in a movie called The Big Lift with Montgomery Clift and Paul Douglas. Others uniformed personnel were American service men. It shows how utterly destroyed Berlin still was when they made the movie there. By the time I saw it, it's rebuilt except for huge open areas with streets but no houses.
