I heard on the radio earlier today, they've done just that.
Most of German nuke plants had not been turned off yet. Fortunately so, they were not yet at the point of no return.
The past 24 hours have seen no attempts at "Thunder Runs" of the sort that saw small isolated convoys enter and then be destroyed in Kharkiv and Sumy and Kyiv.
Also more attacks as civilian infrastructure and populations. Kharkiv was hit by a missile barrage in a residential area, Mariupol also seem to have been. The power is out in Mariupol.
A concern is that as this goes on, ineffective Russian commanders get removed, effective commanders get promoted (effective in the sense of the Russian military). They appear to be getting more risk averse and more willing to use inaccurate stand-off munitions against civilian targets.
This is balanced by the over-reliance on some of the more elite parts of the Russian military, like airborne troops. They have taken heavy casualties.
I am seeing some questions about deployment of some of Russia's newer tanks and other ground equipment - they are just not being seen very often (Armata tanks and such). People are also surprised at the limited use of Russian helicopters - they have thousands, but have only used a few hundred at most, and those in relatively small groups and only for short duration missions.
It almost seems like a Conspiracy Theory at this point (considering the social/political/morale impact that Russia's high casualty rates so far), but some are wondering if Russia is not holding back a big hunk of its best equipped ground forces for a big push. (I don't think so, just mentioning what I have read on twitter by various military analysists who are still surprised at how poorly Russia in performing here).
But the removal of ineffectual officers with replacement via promotion of effective ones is a real thing in war time. Some countries just churn through Generals and officers during wartime, and often end up better for it (like the U.S. in the Civil War, or Russia in WWII). Russia could still begin to show improvement and push the war into a different phase of combat, one more suited to their strengths.
