NATOs power has reduced significantly since the end of the Cold War
I think the past week has proven otherwise.
It's quite clear that Putin didn't anticipate this level of unity.
He even managed to bring unity in the US among democrats and republicans on this issue, more so then any president these past decades has succeeded in doing.
He's also quite surprised at the level of resistance he's meeting in Ukraine. In his blitzkrieg plans, the Ukrainian leadership should have been decapitated by now with most of the country already subdued and a puppet government on the way. Instead, Ukrainians themselves are making a laughing stock of them on the internet and trapping Russians in kill zones with well thought out defense mechanisms.
The morale of the russians is very low. Most of them don't even know why they are there. But Ukrainians know
very well what they are fighting for.
This is a war he can't win. He can win battles. He won't win the war. He can't. This invasion is political suicide.
I think there is a small chance that the world will come out a lot better out of this.
In such scenario, Putin would go the extra mile and escalate further and further... upto a point where his own people turn against him. The ideal scenario here is that his own people put a bullet in his head and do a sweep of the corrupt government and then have a Navalny or alike take over. Russia itself might get on track for Nato membership after that.
In that sense, I think people will look in hindsight at this conflict as the final end of the Soviet era.
These people in power at the moment... these are all the remnants of the Soviets. Putin is a KGB *******, after all. So are many of his "comrades". The russian opposition (most of whom are in jail or poisoned) are a lot more western minded.
