I don't understand what the endgame is supposed to be here. In order to achieve its stated goals (demilitarization, denazification, catching their list of enemies), Russia needs to occupy (which they said they won't, which makes no sense). There's no way Ukraine's govt can agree to or implement these demands.

So Russia will in fact need to occupy Ukraine and install a puppet govt. But how the are they ever going to get out of there ever again? That new government will get removed as soon as they leave.

So long term occupation it has to be, which will be a total disaster and that's on top of the sanctions. Russia just fucked itself, no? How does any of this make sense?
