No, lmao. The Russian Federation is nowhere near powerful enough for that, nor do they have an actual material nor ideological reason for that. It's pretty clear that the Russian Federation simply hates NATO being on its border, especially Ukraine, and is thus trying to demillitarize Ukraine by any means necessary so that it can no longer consider it a potential threat.

There aren't grand delusions of world conquest, nor is there any evidence of a larger plan. If they wanted World Domination, then they would have expanded beyond Ukraine by now in the Russo-Ukrainian war. They haven't, and instead we are seeing pushes for peace talks now that it looks like such talks will be clearly in Russia's favor. If they wanted global conquest, why stop before taking all of Ukraine? Why Ukraine specifically?

I understand detesting the invasion on moral grounds, but inventing reasons just because they sound more scary doesn't get you any closer to solving the problem and ending the war.
