Some of us call it "business as usual," since it really began far earlier than 50 years ago. The first case of U.S. military intervention outside North America was the Spanish-American War in the Philippines, which took place before the Soviet Union even existed.

Thankfully your fellow countrymen are growing impatient with liberals like you and the grownups are back in charge. Maybe you can run away to Seattle. :)
