And that has absolutely nothing to do with anything I said; your claim was that Crimea was populated with Russians since Rurik, which is maybe true but extremely misleading because it constituted a percentage point or two at best. Bringing up the Ukrainian population accounts for nought unless you're suggesting expelling all the Slavs from Crimea and returning it to Tatar rule.

> The Ukrainian claim to Crimea is weaker than Russia's.

The Ukrainian claim to Crimea is stronger because they have a legal basis to its claim. If we return to a state of the world where claims to land are made on the basis of 'my group lives here, therefore it's ours', we will inevitably reap the consequences of post-war Europe.

On the same logic, Germany had a stronger claim to the Sudetenland than Czechoslovakia. But what did that get the Germans in the end? Complete expulsion from the Sudetenland.
