Last 20 years russia invaded Georgia and twice Ukraine. Any attempt to find peaceful resolution post 2014 invasion was made impossible by russia. They were amassing troops around Ukraine since early 2019 and likely prepared for this since Minsk II was signed in 2015. That agreement eventually ended up with russia deciding that Minsk II no longer existed in 2022 and invading 2 days later based on made up excuses. These are the “security guarantees” they have been asking for. They never had any intention stopping their invasion, they just needed pause to prepare for another offensive. And they are doing exactly the same now.
