Russia annexed ukraine, so it's too late tore claim it. If they wanted to keep it they should have just kept it

Ukraine wasn't annexed. Crimea wasn't either. It's majority ethnic Russian and actually was Russian territory up until Khrushchev gave it to what was the Ukrainian SSR.

Also, Liechtenstein is a poor example since it's surrounded by one of the most neutral countries in the world, Switzerland.
