But for Trump's scheme to work you would have to vet every person from every country. Everyone coming in would require a visa, regardless of the country they came from. Would you like to go through that when you traveled abroad? I wouldn't.
Yes, we should base our national security on what foreigners want.
My concern, since we are talking respectfully and exchanging ideas - thank you for that, is that a Syrian that moved to France and just got citizenship could travel here easily. Obviously France has vetting problems. As do many European countries. So our safety will depend on how good a job other countries do. That makes me nervous.
And then there’s that passport machine ISIS stole. That makes me even more nervous.
There’s too many ways around it.
You would have to vet no one if you just shut down immigration entirely and most freepers would be fine with that. We don't need to continue flooding the country with more dependent democratic voters.
