One thing is supporting political groups in another country that benefit you, which is something all countries do. Another thing is annexing territory of another country, that was given to that country by your previous shared and fair agreement. That agreement also mandated Ukraine to give up its nuclear weapons under guarantees that Russia will not threaten it’s territorial borders. This is how WW2 started - Hitler’s pretense was that he wanted to protect and unite the territories full of Germans that want to be part of fatherland and that were lost in WW1.
