The Muslims in this country are nothing compared to the ones in Europe. Why do you suppose this is? Nato relies on us to lead, and this administration has been leading from behind. We can define with much accuracy where the bulk of the Big groups are, we carpet bomb the fuk out of those strong holds. You're right, the lone wolves are hard to detect. But by cutting the head off the snake will dramatically defund and shrink the radicals down a lot. Do you want a revolving door like Europe has and our cluster fuk on our southern border? BUILD THE FUKING WALL...and make Mexico pay for it and they will trust me. We have a 50 billion dollar trade deficit to Mexico and the cost of the fence is 10 billion, you do the math. Mexico needs us more than we need them.
