I don't get this, so they take over another country near their border. What is the objective downside for the rest of the world and the people affected? We already don't care enough to "help" the Russian people, so why care about adding more of them into the fold? If we really cared and if we thought their suffering was worth the price to pay, we would be invading Russia and Ukraine right now to "liberate" the people. Instead we're weighing up the cost of people's lives and playing word games, perpetually.
