I hope that is true, but if it is, whilst obviously positive, I can see this happening again in a few years, in Ukraine or somewhere else when Russia restocks their military.
As you say, they overreached, and now they can claim they were only after the Donbas anyway, spin it as a win in Russia, and no-one learns anything. We need to punish these f**kers, and make it absolutely clear that being a dickless, piece of warmongering s**t does not get results.
China are watching with maps of Taiwan at the ready.
