Not much, there isn't much Putin could do in the military sense without completely crippling the economy. All he can in foreign affairs is bullying small neighbors. Soviet Union was up to 7-8% of the world GDP and had Soviet Bloc - allies that (not counting China - it was never a Soviet ally really) combined had almost as much. Currently Russia has no allies - not even Belarus - nobody recognized Crimea annexation for example. A few weak post-soviet states could make pro-Russian statements once a while in exchange for another shipment of cheap natural gas, but that's about it. And it is currently less than 3% of the world's GDP. It should be too obvious even for Putin that an attempt of a new Cold War will be laughable. So he won't start another war or seriously threaten West. Victims of his policies will be, in their overwhelming majority, Russian people.
