Indeed they have, and it's a brilliant tactic forcing Islamic terrorists and Neo Nazis coup leftists to kill one another off.
Chechnya is ruled by a Russian puppet named Kadyrov, who is currently establishing Sharia and does so with the blessing of the Kremlin.
Indeed it is, and that is because Russia completely defeated and subjugated Chechnya and it's entire terrorist supporting military after Chechnya's terrorists attacked and destroyed several civilian targets in Russia including the Belsan grade school and murdered hundreds of Russian children.
Russia co-opted Chechnya's military and forced them to hunt and kill their own bretheren terrorists, and any other Islamic terrorists or Nazis as ordered. The only other to so defeat and control Islamic murdering hordes with fear, was Vlad the Impaler. Now Chechnya works for Russia instead of ISIS or the Caliphate. Only a Homofascista would have a problem with this.
Russia, of course, also supports Iran's nuclear program...
But not as much as Obama, Kerry, McCain, Jarrett Hilary, Huma, or the American Socialist DemoRat Party.
Russia has also been accused by former KGB/FSB defectors of having intimate ties to Al-Qaueda and worldwide Islamic terrorism in general.
By defectors seeking to please the Obama regime, the regime that actually DID create and arm ISIS, "Arab Spring", and George Soros' Islamonazi Maiden coup, all endorsed by Greetings_Puny_Humans.
