Of course. The Left blames the United States for ALL evil in the world, whether we supported the people who did it or opposed them.
If we supported them, they say, "See. We supported them so it is our fault." If we opposed them, as in the case of the Khmer Rouge, they say, "See. We opposed them and made them angry. That is why they did this. So it is our fault."
The atrocities committed by Stalin are our fault because we sent troops to Russia in 1917 to oppose the communists. The tyranny of Castro is our fault because we embargo Cuba.
The tyranny of Samoza in Nicargaua was our fault because we supported him. The tyranny of the Sandinistas was our fault because we supported the Contras.
Saddam Hussein is our fault because we supported Iraq against Iran. Ayatolla Khomeini was our fault because we supported the Shah.
Do you get the picture?
Brilliant, thank you!
