No way is Iran that stupid.
Weird thing is, when I watch FOX news, I hear the leader of Iran is making all these threats about killing us. Then, in interviews, he talks tough about standing his ground but does not spew the rhetoric.
My guess is that he has to talk tough for his people to keep his job. But after seeing the US decimate the area, they wouldn't be stupid enough to send a rowboat full of TNT to sink one of our ships. It would be suicide, and I don't see it happening.
I have to wonder how hard Bush/Blair is praying that one of their people can invent an iranian connection to this latest foiled plot, so they can justify bombing the crap outta them.
