That sounds exactly like Putin's plan - change the EU regimes so they play nice with Russia and reduce the ability of Ukrainians to wage conventional war, it's btw the official version - demilitarisation of the Ukraine.
This is the real problem in the current situation - everybody is trying outplay each other by using different kind of force (military, economical) and nobody wants to sit down, listen to each other's concerns and try to develop some acceptable peaceful solution together.
This is a reactive plan, not an aggressive plan as Putin's apparently is. It is not the same.
After the events of the last few days, it would seem you are quite mistaken if you think the west as a whole is interested in "developing a peaceful solution together" with Russia. We are first and foremost extricating our economy entirely from Russia at least in the short to medium term. I think you fail to grasp that this is now being seen as an idealogical conflict, not a conventional rivalry between fundamentally like-minded foes. At least as long as the current Russian regime is in power.
We heard Putin's nonsense concerns - he accused Ukraine leadership of being literal Nazis. The President of Ukraine is Jewish and his family survived the holocaust. Putin has lied every step of the way. And you want us to sit down so he can tell more lies?
