As an American, I have to say this is a threat to us also, and I think deliberately so. As such, it can be construed as an act of war. Perhaps POTUS could mention this to the little, mincing coward? "Back off with the plans to be the launching pad for a Muslim invasion of the United States, or we're going to have to do something. And we don't know what that something is, because everyone always backs off when we get serious . . . and we're damned serious!"
