I'm amazed that after consideration, you disagree on the rest.At least we agree on my last point.
Indeed.The overestimation of his own military strength would likely have provided the biggest shock of all to Putin. To be out fought, out thought, and 'out-propaganda-ed', by Ukraine (who he described as 'Little Russians'), and therefore comprehensively disabused of his superiority complex, must have hit him hard, reducing his chances of reversing the perceived travesty of the break up of the Soviet Union.
It seems likely he'd like to stall for time and look for other ways he can and make any sort of progress, but I can't see how that equates to being at his most dangerous. His most dangerous (barring starting a nuclear war, which may not even be within his control) is surely when he has a powerful army to throw about. Stalling for time is hardly more dangerous than waging war.But is he now at his most dangerous? Some weeks ago, the Royal United Services Institute predicted that, as he continues to lose the ground war, we should expect an increase in activity on other fronts in his hybrid war. They also predicted he would stall for time. To manufacture more weapons, to re-arm, and to work on dividing the unity of the west.
He does seem to be a bit stuck. He can't just stop and declare victory, because Ukraine will keep fighting. And obviously he can't admit defeat, so he has to just keep fighting and hoping it works.Today, inspite of a weakened Russia, Putin is as belligerent as ever. He has just announced plans to increase his military spend. He isn't going to stop until he is stopped.
