Of course the parallel with Israel exists only really in the issue of the Crimean Tartars (who have a far greater claim to the peninsula than Russia or Ukraine) exiled by Stalin, but returned gradually during the period of Crimea's autonomous status within the Ukrainian starte but since once again sadly persecuted.
One can argue until the cows come home about historical rights, but those arguments overlook the illegal manner of Crimea's annexation, involving covert military occupation, intimidation, armed commandeering of the parliament in Simferopol, and a faked referendum.
The reason I say it's largely irrelevant at the moment though is that now a war has been started by Russia, all bets are off as to what may happen on the ground. If Ukraine retakes neighbouring Kherson (a process which seems to have started) then in theory they could keep going.
Of course if Putin did lose Crimea militarily that would be the ultimate humiliation. But this is all supposition for now.
