To be fair the 'border' hasn't moved all that much in over 2 years now, save a few fields and ruined hamlets.

Plus they use starlink of drone boats, so some degree of flexibility is needed.

Crimea is Russian-occupied Ukrainian land. There’s not much of a dispute, in that it is exclusively Russia who claims it as part of Russia; Belarus doesn’t count, as it may as well just be a puppet state at this point.

The rest of the world sees it as Russian-occupied Ukrainian land.

I think it’s not occupied land as in occupied by force against the will of the inhabitants. The majority of people of Crimea participated in the referendum of which one option was to join the Russian Federation and this choice got the most votes. There are conflicts in international law about “Self-determination versus territorial integrity”[0] which contradict each other like the people of a region want self-determination while the state says it’s illegal. Sometimes it doesn’t work like in Catalonia, sometimes it works like in Kosovo or in a little bit more distant time when a referendum was held to make Hawaii the 50th state after the US annexed it.

That referendum occurred after the annexation, and with Russian forces at each of the polls. It had a 97% approval.

In other news, Putin is totally a democratically-elected President, and not at all corrupt.
