I can’t believe that no one understood the simple fact that you dance with what brung you. I ranted about it a while ago and no one I have seen ever recognized it. Putin had what he had when he invaded and nothing else. You can’t resupply an armed force with supplies you don’t have. If energy prices go up, that doesn’t instantly create new tanks and planes and rockets. That takes time and that is why Russia is bogged down. Putin incorrectly thought he could overrun Ukraine in a couple of days with his actually old and outdated equipment. Now that he couldn’t do it, he can’t resupply his troops. He was falsely confident and didn’t consider that his plan was flawed. And that may be the reason that he is claiming to back off so he can actually resupply his offensive.
