No. It is a result of failure to deport them, which should have happened long ago.
We have, in the U.S., foreign-born Mohammedans known to be hostile to America, and we continue to keep them in our country. Why?
Deporting them will not help.
They need to be eliminated.
Remember the Godfather? "Keep your friends close and your enemies closer" There is truth in this. The terrorists we know of in America are probably a good source of intel for us, whether the terrorists themselves know it or not.
