I partially agree - indeed, we can not change the culture or violence of Afghanistan, especially with our own phony, multi-culti, politically-correct delusions playing in the background.
But leave Af-Pak, and what does one do when it again becomes a base for some Sunni terror group, attracting Muslim youth from across North America and Europe?
Will we do the next most reasonable thing - ban any Muslim visitor from South Asia? Ban travel?
I highly doubt it.
So what it if attracts Muslims from the US and Europe? Just don’t let them come back. If they want to fight in their own third world dumps, let them. Keep them out of civilized countries. Not going to happen, you say? Then we will continue along the path of futile war in Afghanistan, Iraq, Syria, etc. because the problem is Islam, and the only possible victory would be the destruction of Islam. How is that possible?
