Ukraine is through the heart of the winter and Russia is now turning out the lights with these power plant hits. Putin let them keep their heat for the winter, but I think things are about to get less static. Notice no talk of any "summer counteroffensive" on the Ukraine side (that's all we heard about 12 months ago). It bodes for a Russian summer push.
Before, it appeared that both sides were playing "not to lose." Now that Putin secured an overwhelming reelection, he's more likely to get aggressive. OTOH, Biden desperately needs to not lose this war before election. This summer will see if US .mil has developed any new tricks or wunderwaffen. NATO mobilization is madness and just impractical. Ukraine can only equip, train, and arm so many men at one time. Advantage Russia.
My 2 cents at least.
That's actually an excellent point about leaving the power and heat on for the winter, seems like they are trying as much as possible to keep the civilian population out of the crossfire and minimize the effects of the smo.
Contrast that with the other side actively targeting civilian areas and doing "double taps" when the emergency personal respond to the initial strikes.
Not really expecting any big arrow pushes or large, all out assaults this summer, it would seem RU will just keep the pressure all along the line and slowly chip away at the defenses. It has been working quite well so far, why make big changes?
