World War II (American soil was attacked although we provoked the Japanese by cutting off their oil supply and other trade embargos), and Afghanistan (American soil was attacked). Although without America's military interventionism in World War I, Hitler never would have come to power and there never would have been a World War II, but that's another story. And Afghanistan would most likely have been avoided if our military had been in America instead of being spread over the globe like the Roman or English Empires pissing off everyone else with our bullying and muscle flexing.

The Constitution defines our military to be used for the DEFENSE of American soil and ships. DEFENSE never includes starting unprovoked wars, using our military to defend other countries, humanitarian aid missions, training other militaries, peace keeping missions, etc.
