Some people make a convincing case saying Kadyrov might as well say he won the Chechen war. Moscow is paying him tribute every year and he has a free hand to build his islamic state. He has already banned alcohol and de facto legalized polygamy.
Moscow does not rule in Chechnya. Kadyrov has banned entry of federal forces not under his control. Fighting in Putin’s wars is just training the troops loyal only to him.
Quite a short sighted policy from Putin if you ask me, but then again I have never bought into the story of Putin or Russians in general being masters of strategy. Just a short time ago they strategically played themselves into the position where they didn’t even have toilet paper and had to beg their western enemies for food aid.
