If the US are clever, they'll stay out of Iran. Iranian students are already rebelling against the government, and a full-scale revolt doesn't seem unlikely. This is what should have happened in Iraq. If Iraqis wanted to get rid of Saddam, the Iraqis should have started a revolution, not the Americans. Unless most Iraqis didn't want to get rid of him...
Also, don't forget that according to Bush, Cuba is also one of the most dangerous and evil countries in the world. Fear the Cubans!
Signatures are for fools.
