not just to hurt infrastructure and civilians. They are simply very weak
Running out of ideas, to some extent.
The first two years of the war we fought like Lancelot.
The entire time, the Russian military "blogging" class, and servicemen themselves grumbled about:
1) "Why don't we destroy every crossing from the EU into Ukraine, so they cannot receive supplies? Our leaders have betrayed us in a back room deal with NATO!"
2) "Why don't we destroy all the bridges crossing the Dnieper and so divide Ukraine in half - making West-East logistics impossible?"
3) "Ahhh! Ukraine's rail capacity is largely electrified. We have to hit substations and transmission lines to turn off the trains! Why are we not doing this!"
4) "There's no such thing as 'civilian' power generating capacity, since it feeds Ukrainian military industry. Destroy power generation."
Gerasimov and Co. ignored all these rants for close to two years, and tried to win the war in chivalrous fashion. When that didn't work, they slowly started checking off items from the "moaning blogging class'" wishlist. Of course - none of the things the bloggers promised us would happen - happened.
Instead, Ukraine got really butthurt about finding a way to respond - and started bombing our energy infrastructure.
Then several ceasefires followed, where we agreed not to touch each other. Inevitably they were violated, by either side, whenever it felt under pressure and wanted to lash out.
The current Russian infrastructure strikes are largely intended to force the Ukrainians to come back to the table, and agree to stop hitting our oil and gas infrastructure.
It has been conclusively demonstrated that destroying Ukraine's grid had minimal effect on the actual frontline. Trump should also take note of this.
