A better solution if there is a legitimate terror threat is to process potential refugees through territories such as guam
You can't just shuffle people around like cattle. If you expect these people to integrate into the American community, detaining them in Guam is not going to be helpful.
Refugees by definition intend to go back to their country of origin once the conflict is over, they are not immigrants. We can protect and take care of refugees while still keeping track of them
What happens when the refugees enjoy living in a 1st world country and don't want to go back to a war zone?
