I'm also wondering what damage this kind of approach will do to intelligence gathering and sharing.

Are these clowns really going to deny entry to citizens of these countries who already have US immigrant status? It seems so when they say suspend entry for 30 days to non-immigrants and immigrants from such countries unless they have diplomatic visas, NATO visas or C-2/UN visas.
