If this report is accurate, you have to wonder what kind of reprisals they have in mind. Should Iran be attacked, I doubt they have plans to retaliate with individual suicide bombers, despite what they've said about their thousands of supposed volunteers. I'm more concerned with the fact they've met with people in Syria, where Saddam's chemical weapons were supposedly moved. Access to that type of munition could put teeth into their bluster. With their seeming eagerness to start a regional conflagration, I wouldn't put it past them.

The suicide bombers will probably make their way to the West Bank and Gaza for strikes against Israel, and throughout the Persian Gulf for strikes against American forces as well as our embassies and consulates.
