Kick radicals out

If people wish to fight and die for ISIS, the caliphate, and Islamic extremism

then kick them out of the country. Simply put, they are going to cause problems with terror strikes, causing massive fear, police safety situations, and the loss of life and property of hapless innocent victims.  The cost to society is greater if they stay.

Kick them out to the caliphate. They don't kill our people and we can deal with them by cluster bomb later.
