It's not just the war in Ukraine Putin lost, he lost the spy war and I'll bet his focus will be there. Ukraine provides a launching pad deep into Vlad's empire with lot's of potential human resources for the CIA and they will be going after Belarus and so will the Ukrainians. It also opens up the Black sea and the neighboring former republics are close by and this war puts the CIA right in the middle of the mess being created. Soon Vlad will have many fires to put out and stretch his resources, some of the guns going there will end up in these republics under Putin's thumb. Vlad opened the door for this shit, Ukraine is not a NATO member, it is an independent nation that does not fear Vlad since he's already doing everything he can to harm them.
A note: Vlad would have used tactical nukes already in Ukraine if he did not fear the consequences, he would have done it days ago when he knew he was not only loosing, but was being humiliated. Vlad just acts like a wild and crazy guy when it suits his purposes, he's not unstable, he's pissed and frustrated. He might be delusional, but aren't we all to some degree or another? He ain't nowhere near gone as a typical Trumper, but most dictators end up swallowing their own shit eventually, their own propaganda affects them too after a time.
Vlad's dreams are shattered, he even lost the spy game and Ukraine will bleed his army white and destroy much of his equipment that won't be replaced with a shattered economy in freefall. NATO is looking at this as an investment in the future and by the time Vlad is done his army will be destroyed and the threat removed, much of the perceived threat has been removed already. A little more than a year ago Vlad had the world by the nuts and the POTUS in his pocket, until Biden won the election. It must hurt like Hell to be so humiliated, he will be remembered for his blunders and ruining the country.
