I believe it has already begun in the USA. I consider the Ft. Hood atrocity that was committed by that Muslim infiltrator to be the start of this kind of "jihad" here in the USA. And then there was that Muslim attack in Boston a few weeks ago. Yes, it has started. And the Muslim alien in the White House encourages it.
Also the Little Rock Armed Forces Recruiting Center shooting by the jihadi convert; the Times Square bombing attempt, the underwear bomber...
Don’t forget the Beltway Snipers, Ark Recruiting Station shooter, numerous ‘honor killings’ etc.
There are literally millions of “soft targets” in the US. Just wait until the murderous muzzie terror cells get their “go orders” from Iran. Beslan will become “the new normal”.
