Guatemala. Argentina. Vietnam. Fallujah. Colombia. Venezuela. Look 'em up.
Just for balance, and to show I'm not just bashing 'Murrica for the hell of it, read up on a little island called Diego Garcia in the Indian Ocean. The British (my) government should be hung out to dry for that little fiasco. (To summarise, it was a British territory up until the 60s, when the government decided to sell it to America so they could build a huge airfield on it. Unfortunately, there were a few thousand people living there. So the government had all their animals killed, loaded them on ships and dumped them on the quayside in Mauritius.)
