That does nothing to address the concerns I brought up about how our foreign policy affects the recruitment of terrorist organizations. Trump's "muslim ban" rhetoric feeds their narrative that the west is at war with Islam. Do you have contrary evidence?

Terrorist attacks carried out in the U.S. by immigrants didn't come from any of the countries we banned (they came from Egypt, Saudi Arabia and the U.A.E.). By your logic we would have to ban every country where a potential terrorist immigrant COULD come from. The only way to be safe would be to block immigration from all countries. But even then, a decent number of ISIS-claimed terrorist attacks were homegrown. It's an unrealistic game of whack-a-mole.

That logic is akin to "well the only way to prevent traffic accidents is to not drive!". I fear Trump is playing you for a fool if you think it's that simple.
