Putin might not be interested in Alaska (yet?), but he certainly has his eye on Moldova, Estonia, Latvia, Lithuania, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Georgia... Belarus may be a close ally for now, but that can always change. Armenia and Azerbaijan have already been goaded into skirmishes with each other, which will leave them both weakened. If Putin's dream of a "reunified" Russia including of all the former Soviet Republics isn't halted, other countries - Mongolia, the Eastern European countries, even Finland, are also all at risk. That will lead to serious disruptions worldwide, even in the 2/3 of the world that stays out of it. And with the wealthier countries distracted with Putin's wars, other countries with their own expansion plans will be freer to pursue them (China with Taiwan, India and Pakistan with the Jammu and Kashmir territories, for example).
