Last year, Sen. John McCain (R-AZ) joked about bombing Iran to the theme of the Beach Boy’s “Barbara Ann.” McCain was widely criticized for the remark, but simply told critics to “lighten up and get a life.” The Washington Post notes that McCain tried joking about “killing” Iranians again today:

Responding to a question about a survey that shows increased exports to Iran, mainly from cigarettes, McCain said, “Maybe thats a way of killing them.” He quickly caught himself, saying “I meant that as a joke” as his wife, Cindy, poked him in the back.
According to a report released today, U.S. exports to Iran “grew more than tenfold during President Bush’s years in office even as he accused Iran of nuclear ambitions and helping terrorists. America sent more cigarettes to Iran, at least $158 million worth under Bush, than any other products.”
