At some point, the USA will simply need to BAN Muslims coming from most areas of South Asia, the mid-east and North Africa.
No one wants to stay in Af-Pak forever, or wage endless war in Syria, and we can’t play whack-a-mole with radical Islam forever either.
The only thing left to confront at that point then is our own political correctness and the massive forces of leftist destruction that reside within our own country.
And from Europe ... that's going to be the tricky one.
“No one wants to stay in Af-Pak forever, or wage endless war in Syria”
Actually, yes they do. The people the 12 billion a year gets funneled to them do. The Generals do because they get to have command combat duty and rub elbows in a joint operation with NATO. They also think Afghanistan lets them have a base to threaten central Asia and China (because we don’t have enough wars going on right now....)
And of course, the neocons do because they are going to rebuild the entire middle east and cannot stop fellating their Sunni money man masters.
Some of our generals have described it as a Generational war and casually note that we have been in Germany and Japan for 70 years.
They see Afghanistan as exactly the same.
They literally do want it to go on forever.
