Ariel May Be Getting An Itchy Trigger Finger

American envoy John Bolton, the State Department's top international security official, repeated U.S. allegations Monday about an Iranian nuclear weapons program and said Israel might attack Iran's nuclear sites because the Jewish state has "a history" of such actions.

"The vice president said we're very concerned that this might happen," Bolton said, referring to a recent statement by U.S. Vice President Dick Cheney. "Israel destroyed the Osirak reactor in Iraq. They have a history of this," Bolton said.

Earlier this month Cheney said it was possible Israel might attack Iran if it became convinced Tehran posed a nuclear threat.
