The Kherson Oblast has been annexed
Most of Kherson was occupied, but not all. Putin declared he had annexed all of it, but then lost the capital of the oblast. Now he is slowly losing the rest of the oblast.
Whether he can legally annex land he occupies is one question, but he certainly cannot actually annex land he does not occupy. Dukkkha's post did not age well.
As to Odesa: the anti ship missiles have kept the Russian unable to use much naval assets
but I have to think that's next on Putin's list (not Kyiv)
We are seeing this over and over again. Putin throws everything he can find into attacking, but then runs out of steam, and collapses. The fact is Russia is not as strong as we have been led to believe. They were not able to take Odesa, and now are stuck retreating.
