Radical Islam will always exist as long as Islam exists. How about we protect our own borders and quit letting more Muslims in our country. That’s the real solution, not getting sucked into Central Asian quagmires.
Just remember what Rumsfeld said: we can fight them over there or we can fight them over here.
IOW we need to fight them and defeat them “over there”, so they won’t come “over here “ to attack us and murder us.
