And no one can predict the future, or say with certainty what someone else is going to do. What you CAN do is select the policy which has the best risk/benefit ratio, the most likely chance of succeeding, and then monitor it and adjust it if it becomes necessary.

Bringing in the refugees has risks, you may bring in undesirable people (not just terrorists, but criminals), sick people, even good people who just won't take to our way of life, or who may overwhelm our resources. It will also crowd out other immigrants we may like to have, like highly educated foreign workers and potential entrepreneurs.

On the other hand, We show middle easterners, ISIS' victims, and the world in general that we welcome and reject no one simply because of their race or religion, which pretty much blows the terrorists' propaganda right out of the water and makes their job much harder. They have to explain to the people they are trying to conquer why Arabs and Muslims would rather come to the Great Satan than reside in the Caliphate.

Sure, things can go wrong, especially if we don't monitor and correct the program, as I pointed out in the opening post to this thread. We must make sure the influx of refugees is controlled and regulated. But its worth the risk, its what America has always done, and its the right thing to do. Besides, I believe experience has shown people who are willing to risk it all for a fresh start in a strange land are, as a rule, just better people.

I have relatives who came here as refugees, seeking freedom. My ancestors came here from another country. So did yours. Now we have to pay it back.
