US May Deny Visa To Iranian Head of State

The U.S. is considering denying a visa to newly elected Iranian Mahmoud Ahmadi-Nejad to speak at the UN Assembly. I have no problem with this - whether he was culpable of participating in the 1979 U.S. hostage crisis or not. If he did participate, then there is no doubt he should be denied to enter the U.S. If he did not participate, he still should be denied entry. And the same goes for Fidel Castro, Kim Jong Il, Robert Mugabe, Hugo Chavez, or any other dictatorial tyrant.
