Dude, you may be surprised, but Chechen terrorists are muslims unfortunately. And the only fight is between mainly Christian Russia and mainly Muslim Chechenya. Until it was a communist state the problem did not occur. Just for your information, Uighur terrorists, largely unheard, of China, are also Muslims, and so are Kashmir ones, and so are Somalis, and so are Afghans and so on... The point is not so much of religion, the point is, almost all of these have a common ground in Pakistan.
