Watch The Mouse That Roared

A cold war satire erupts when the tiniest nation in the world declares war on the United States so that it can intentionally lose the war. The nation's sole export and income is a rare wine that's now been duplicated by a competitor. The nation's treasury has no more money. By losing the war it can apply for foreign aid that the country wouldn't otherwise get.

Rather than losing the war, the world's smallest nation invades the United States but wins the war. They return home though with a golden egg.
