I wish I could say we were the ones responsible, but that’s incredibly unlikely. I’m also not sure Mossad was responsible. I wouldn’t be surprised, but I’m also not sure. Iran has plenty of enemies, including Arab ones like Saudi Arabia. Perhaps the only people more opposed to Iran’s nuclear program than the Israelis are the Saudis.

(AP) TEHRAN, Iran – A pair of gunmen firing from motorcycles killed an Iranian physicist involved in the country’s disputed nuclear program on Saturday in an attack similar to other recent assassinations of scientists that Tehran blamed on the U.S. and Israel.

The slaying is sure to add to tension with the West, as Iran moves ahead with an atomic program that four rounds of U.N. sanctions have failed to slow.

The target, identified in Iranian media reports as 35-year-old Darioush Rezaei, was a physics professor whose area of expertise was neutron transport, which lies at the heart of nuclear chain reactions in reactors and bombs. One of the earlier assassinations, in November, killed a man with the same specialization.

I also wish I could say I feel some sadness that this happened. But I can’t. Rezaei was helping Iran acquire nuclear weapons. Iran is a state-sponsor of terrorism that openly fantasizes about destroying Israel, the United States, and the west in general. Iran is an enemy trying to acquire nukes. Rezaei was helping Iran do just that.

The hit sounds like it was professional. Rezaei was driving home with his wife and daughter at the time, but only he was killed. His wife was injured but survived. His daughter is apparently fine. Rezaei was shot in the neck by individuals on motorcycles. The men got away. No one has been arrested as of yet.
