If there is a terrorist attack on the US, I think it will be in the last year of O's reign and prolly in the last six months.
Saying that, think about it. What advantage would it be to the world muzlim movement to attack the US during a brothers presidency. Really, the political, social and diplomatic scenes are, favourable, more favourable to the izlamic world today in the US than at any time in this nation's history.
Mosques going up everywhere as in Britain.
more later, gotta get ready for a meeting!
