Russia is going to grind down Ukraine.
Unless Nato/US sends in troops and escalates it doesn't look good for the Ukrainians.
As soon as the peace agreement is signed, the areas are annexed - it's gonna be a repeat of Afghanistan during the US occupation.
Bombings, assassinations, disruption, etc. Ukraine nationalists will make occupation very expensive to Russia. And the CIA will be there to assist.
The real question then becomes, will Russia try to grab more territory?
It's the same question that folks had after Russia annexed Crimea, and we know how that played out.
Still, grabbing up the rest of their protection zone only happens if Putin, or the old school Soviet hardliners are still running things, imo.
Putins revanchist speech around the start of the war made his objectives exceedingly clear: restoration of Imperial Russias borders, whether by force (Ukraine invasion '22) or by politics (Union State with Belarus)
So as of March 2023 Russia has control over:
Eastern Ukraine and Crimea
Northern and Central Georgia
Transnistria in Moldova
And has de facto annexed Belarus
All of these countries are target to be fully annexed into the Russian Federation at this point. Dont believe that "Putin wants the Donbass" shyt, he wants UKRAINE. He made clear that historically Ukraine is just a mash up of Russian and Polish territory.
They will definitely move on these other countries/regions unless stopped:
Kazakhstan - the whole North and several provinces are majority ethnic Russians and there are many Kazakhs who would sell out for the Russians. They need to watch themselves cause they dont have the West backing them like Ukraine. Theres 9 million ethnic Russians in Ukraine and 3.5 million in Kazakh, theyre definitely going there. They also used military force there just last year so they know the layout of the land and what the Kazakh security forces operate like.
Japan: Im 100 percent sure the Russians will try to militarize the Kuril/Northern territory islands now to be able to have a knockout 1st strike capability against any US forces in the region that might operate in the Russian Far East in a war against Moscow. They might even claim several new islands that Japan just found in that area.
Kaliningrad: See my reasons above for why Kaliningrad will be even more militarized than before. The country in Europe with the largest Russian population is Germany. If the Russians feel war with NATO is inevitable they will strike at Berlin first and use that as an excuse, that Germany was starting a second Russophobic holocaust and they needed to be taken out. Complete and utter bullshyt but nuclear missiles from Kaliningrad can destroy most of Central Europe within 5 to 10 minutes and US/NATO forces along with it. Thats why Germany is acting so scary, it would actually be easier for the Russians to nuke Berlin with their medium range missiles than they could Warsaw, unless they station them in Minsk (as they're threatening to do)
