Invasion, U.S.A. (1952)

Five people are sitting in a New York bar with a mysterious Mr. Ohman, when they hear the news that the godless Communists are invading the good ol' U.S. of A. The five rush off to various sections of the country to do their part to stop the invasion, when an A-bomb crashes down upon Manhattan.

This incredibly cheap film is not without its entertaining moments. While America is being invaded by The Enemy, the President appears on television to assure the nation that the US military is exacting vengeance on Russia - for every atom bomb dropped on the US, three are being dropped on Russia! While this sounds comforting, it merely proves the key to Russia's success, since the Russians have already transported everything they'll need to win the war. By devoting so much energy to attacking the Russians on their own soil, the US fails to defend itself against the invading Russian army. Apparently national "defense" is an alien concept, for a nation accustomed to fighting its wars overseas.
