And now we get to the question: what is his new victory condition? The desired one -- which seems to have been quickly toppling the Ukrainian government, hopefully installing (at least temporarily) a more Russia-friendly government and solidifying the breakaway republics in the East -- isn't going to work out. He can still accomplish those goals, but it's quite clear that such a government wouldn't last a week unless Russian troops continue to occupy the country, and would be replaced by an even more stridently anti-Russian government the second they leave.
So, does he:
- Knock off the Ukrainian government and GTFO, allowing Russia to declare victory and pull back to Belarus and the breakaways while maintaining a war footing, with no real agreement;
- Attempt to occupy Ukraine long enough to have some sort of sham election that would give them a government that would put to paper some of their demands on the breakaways/Crimea;
- Take some sort of peace deal with Ukraine in a week or two that gives some sort of recognition to the autonomy of the breakaways (short of actual independence) and no agreement on Crimea.
Because #3 is the most achievable pseudo-victory, but it's also so transparently a loss that it will be enormously damaging to his position. #1 is also likely achieveable, but means that Russia will be stretched thin ensuring that an emboldened Ukraine doesn't try to take the breakaways by force, and means a long-term crisis that will get extremely expensive for Russia. #2 is the only actual victory, but it would be unimaginably costly, and relies on the Russian army to hold a hostile country for probably a year, minimum.
