Nonsense.
The Minsk agreements rest on two irreconcilable interpretations of Ukraine’s sovereignty. Firstly, is Ukraine sovereign? as Ukrainians insist, or secondly should its sovereignty be limited, as Russia demands?
Back in the 2000s Ukraine’s President Yushchenko was trying to implement a trade deal and an association agreement with the EU, something any sovereign country should be able to do.
Russia got annoyed to the point whereby it was becoming concerned about the EU’s expanding profile in the non-Baltic post-Soviet space, it started to actively white-ant Ukraine’s governance.....And while it did not take the prospect of an association agreement seriously at first. But by the early 2010's, with the negotiations at an advanced stage, the Kremlin had come around to the view that it was a realistic threat.
It's the Ukrainian relationship with the EU which could and probably would have been replicated with an association agreement with NATO that has been cause of the entire dispute.
Sovereignty mean sovereignty and Ukraine’s relationships with Western bodies like the EU and NATO should be up to their own discretion and not that of the Kremlin.
