I don’t approve of Russian annexation of other parts of Ukraine, but I think their claim on Crimea is more or less legitimate. It was only because of an at-the-time all but meaningless symbolic gesture on the part of Krushchev in the 1950s that the peninsula ever became politically Ukrainian at all—it had been territory governed (with varying degrees of autonomy, and a few periods of conflict, although never specifically with nationalist Ukrainians) by Russia since the late 18th century when the tsars first took it from the Ottomans. It has never in its history been culturally or ethnically Ukrainian-majority.
I think it should return to its former status as some kind of locally-governed autonomous republic or state, and ultimately left to people there to determine their national affiliation.
It’s not as politically or historically clear in other majority-Russophone parts of Ukraine—Odessa, for example, has always been predominantly Russian-speaking, but the city wasn’t just handed to Ukraine recently the way Crimea was. And at least when I visited (a long time ago now), people seemed more than happy to identify as Ukrainians.
I know next to nothing about the conflict zones in the East, except that I am glad I don’t live there.
