Ukraine negotiations: reshuffling the deck in Europe?

Political scientist Ilya Matveev explains in a Facebook post that Russia is unfit as a partner for security agreements:

“By invading Ukraine, the Russian Federation has triggered a new Cold War, and defence spending will now be the sole measure of ‘security’ in Europe. No new treaties can improve Russia’s situation – at least not as long as Putin remains in power, and most likely not even after there are political changes there. For there is absolutely no trust in Russia. Russia has consistently violated all international treaties and declarations. Who, after all that, would still want to play ‘collective security in Europe’ with it? You only have as much security as you have soldiers and drones (and, in the future, nuclear warheads).”
