If democracies let putin commit genocide against Russians, putin will come with the same agenda after the democracies.

The easiest and safest way to free Crimea and stop any other Russian aggressive act in Ukraine is to make a list of 100,000 Putin's top supporters, career state criminals, make it public and then, 10 days later randomly ban for life 500 persons (plus all their family members) a day from ever entering the USA, fifty-three countries members of the Commonwealth, and the European Union.
