Let us be frank, Tancredo voiced a thought that concerns many of us. If Washington D.C. is obliterated there will be a tidal wave of demands that we take out Makka. Also, let us also be frank about something else, should a Muslim bomb take out Tel Aviv then Makka will be ashes.
To be honest, after 9/11 my views were a hell of alot worse then Tancredo.
That said, his point had to do with the threat of retaliation, again them, its going to be spun around, because of the way he answered it.
I'm not even saying he is wrong, I'm saying he phrased himself wrong, and could have worded it better, and wound up giving a throw away line to tag himself with, but either way, I doubt he is worried, this isn't even a story right now anyway.
