Hmmm....well, I haven't fought the VC and you have, but I would rather take on Iraqi insurgents than VC, from what I can see. The VC had more experience than these guys. And the Vietnamese have had a much longer and more effective warrior tradition than the Arabs have recently.
Plus Arabs are pussies.
Well, I haven't fought either, but I understand that the Israelis have a saying: "If we have to have enemies, thank God they're Arabs."
