He is probably wondering what's the difference, then? Why USA helped Albanians on Kosovo,
but in the same situation in Ukraine helped oppressive central government, instead Russians
in Donetsk and Lugansk

^^^ The point seems to be this. Once martial law has been enacted, here is no way to assure that it will ever be repealed. What that means is that the country has lost its constitution, its name, and its identity... at least until the martial law leader removes martial law.

This makes the martial law leader into a quasi-dictator. Even though there are all kinds of protections written into the constitution to keep this from happening, martial law is essentially a suspension of the constitution until the leader voluntarily steps down and reinstates the constitution.

Zelensky-land... until or if he decides to change things back to the constitutional republic that Ukraine was.
