I think the talk about the Mex border is mis-direction. Canada is very friendly to middle easterners. Still, we ought to put lots of troops at both borders, 24 hours per day with orders to shoot to kill. Border Control in other countries has no problem with shooting invaders, we shouldn’t either!
I agree that any talk about a border incident doesn’t make sense. Given the amount of time that ISIS has had to infiltrate the country, a 9/11 attack far inside the US is undoubtedly well within their capabilities.
