Yeah. We stabbed them pretty good too, just from incompetence and miscommunciation.
My international regrets as an American:
1) Treatment of the Nationalist Chinese after WWII
I know they were corrupt as the day is long, but...they didn't kill something like 35 million of their own people
2) Bay of Pigs
Spineless stupidity
3) South Vietnam
Nuff said
4) Shah of Iran
The height of the idiocy, pettiness and stupid misguided righteousness of Jimmy Carter.
5) Shiites in southern Iraq after GW1
That was just ineptness on our part, and lack of thinking things through. I certainly don't think we wanted that to happen to them.
You forgot one: Giving North Korea to the Communists after World War II.
