Not really. That too, of course. But Putin is pretty set on saving both Russia and its Christian Church. And keeping the muslims dazed, confused and paying is doing the job while grabbing influence, which is always positive.
Putin’s interest is only power. Look at Russian economy today. Russia have best agricultural land in the world but imports 70% of the food from other countries. Same with electronics, cars, heavy machinery and more. Aircraft industry practically dead. Military production going down too. Good leader would do everything to elevate his own country out of poverty but nothing is done. The only reason that Russia is afloat is natural resources.
