Americans are pretty violent aren't they?
bombing Iraq and Afghanistan killing 2 million innocents, now Obama wants to invade Pakistan/Iran/N. Korea.
Supported Kosovo Independence from Serbia, dropping bombs on their embassy (I do not recall which).
Supported Chechen Independence rebels against Russia, however that backfired.
Used to support Saddam Hussein too
Supporting the existance of Israel by driving Palestinians out of their own land.
Now they are supporting Tibet Independence by arming those "peaceful" Tibetans with machine guns and rocket launchers so they can rebel against the Chinese.
P.S. KKK isn't more violent as any other groups out there, for example, they don't bomb other countries and steal their resources do they?
Plus they are prohibitionists, anti-abortionists, conservationists and anti-smoking.
Andrew Jackson caused the Trail of Tear, not KKK.
