The danger I see for the US is that if the Muslim Brotherhood gains a substantial slice of the Parliament (they probably will) some elements of the military might wave that as a red flag and try to coax the US into supporting continued military dominance as "the only alternative" to what will be styled as "terrorist rule" or "rule by supporters of and sympathizers with AQ".

I hope we don't fall for it. I'd much rather see the Brothers in Parliament then out on the streets, excluded from power and organizing a rebellion against a tenuous military regime with no shadow of legitimacy.
