The Minsk Agreements were signed with the West explicitly planning to break them and only use them to "buy time" for Ukraine.

The 2022 peace deal would have restored Ukraine's borders. Both sides had agreed to terms until good ol' Boris decided to come through and fuck things up. This has been widely confirmed by officials in Germany, the US, Israel, Russia, and Ukraine.

It's important to understand that Russia's goal in Ukraine isn't to capture territory, but to protect it's heartland from conflict (a la Cuban Missile Crisis, Monroe Doctrine, etc.) Russia's core aim is to prevent NATO from getting ever closer to Moscow because Russian defensive doctrine relies on defence in depth and that falls apart if someone can launch a decapitating strike on your capital with conventional means. It's important to remember that from 1983-1992, Russia had adopted a NFU nuclear policy that was only repealed once it became apparent that NATO would not adopt one in return.
