A lot of people say a lot of things. Kim Jong Il threatened to nuke us. Other Jihadist groups have made similar threats against the US in the last decade. Why does this one frighten you so much more than the others?Oh my! A terrorist group that is attempting to form a state the size of California...that beheads anyone who does not convert to Islam is not threat to us? I bet you thought Al Qeuda was no threat before 9/11/01.
