We can't discriminate against people just because of terrorists coming from there. Maybe if we were more kind to other countries, we can give up nationalism and accept the world.
Then, people like them would have no reason to attack us, and their government would be kinder in helping to get rid of things like that. Republicans want to cut ties and chant MAGA, Democrats want to make up with other countries, give freedom to the oppressed (syrian civil war help), and help everyone, not just the US. You can't make it so every american meal, someone starves in africa.
