Wouldn't you have to wait until Mecca stopped glowing in the dark before you started rebuilding?
As for the Congressman, he's just stating what a lot of people already believe. Stating it in such a public forum is the stupid thing, not what was said.
And if Al-Q or whoever pulled a multi-nuke bombing of NYC, LA, and another city of your choice, I'd have no problem whatsoever with saying goodbye to Mecca...
