Of course not. But it would prevent the entry of any infiltrators known to be present in the group of refugees that are an immediate concern.
And, secondly, limiting the banned countries to the two o immediate concern increases the chance of passage. A comprehensive list of all risky countries wouldn't have any chance of surviving a Democrat filibuster.
And if we include nations with an ISIS presence we inadvertently include our own allies.
As I noted earlier in a post concerning French Muslims, we have to trust our allies to vet their own citizens. If we didn't honor a French passport -- Muslim or not -- we'd run the risk of retaliation against American passport holders. Or trade.
In other words, we'd be playing with diplomatic fire. Imagine how we'd respond if one of our allies refused entry to an American citizen because he was black.
The point is we need to shut down all immigration for the forseeable future.
Immigration hasn’t been for the best interests of THIS country for 2 generations now.
That congress refuses to see what the electorate sees only means big trouble ahead.
