Perhaps the Olympic games should be suspended until the muslims are ALL contained in their desert empires. They have no business here unless we are hell bent on suicide.
I would have put a freeze on immigration from terrorist states. Unfortunately that means almost all Middle-Eastern nations. You could also include much of Southern Asia in that group.
Until these cultures decide to live in peace with others, I would not include them in my list of guests. As you said, unless we’re hell bent on suicide.
It’s not our fault that they are spoon fed doses of hate the U. S. and Western culture in their mosques. It is what it is and we’re stuck with dealing with it like we would a stick of dynamite.
As for the games, we’ve got the camel’s nose inside the tent. It’s too late now to do much of anything other than increase security.
Over time, I’d reduce the amount of people from the regions I mentioned. You can do so if they get out of line at all. Revoke their visas. If they are at all connected to any enterprises that might threaten your populace, deport them anyway.
The onus is on them. It isn’t our fault if they hate us. We don’t have to lay down and die, just because we wish the world was a peaceful place.
