Pt 2/continued: (as they cynically misinterpret it, and lie about the facts of each case) - and also demand a unilateral and ultra vires "right" to act as the world's cop, Judge, Jury and Executioner. It's just pure hypocrisy and cynicism, on a breath-taking and Global scale.
And THIS is the problem with your (Imperial/Dark Brandon Regime) alleged "rules-based international order". When queried about where these "rules" can be found, by Sergei Lavrov, and the Russians, there was never any response. Nor is their any indication as to who wrote these rules, and when - or to whom they would apply. Do they apply to all States and "Organizations" equally, and do they change based upon the situation(, and upon desired outcome of the west and its failing attempts at Global Monopolar Hegemony)? They're clearly not synonymous with the International Law, that the west is constantly violating, and always seeking new ways to subvert and undermine.
As for Istanbul - Ukraine NEVER HAD any Nuclear Weapons of their own. The USSR, had some that were stationed in Ukraine. That's all that was. And the Russians make transparently meritorious claims that the treaty was abrogated by the US/NATO and Ukraine - so one cannot point to the inviolability of a document which one has breached, ones-self. Like I said - unilateral declarations, aren't acts consistent with International Law. Take that case to the ICJ, if you think it has merit.
This principle of non-intervention...it takes some real Chutzpah for the US or its Agents to bring that up. It applies to all parties equally, does it not? If so, the US Government and their "west" Empire, are in perpetual violation of this, around the world - and have been, since at least the end of WWII. The "Orange Revolution" coup attempt, and the successful US coup in 2014, have made a mockery of the concept. Under those circumstances Russia would be foolish to adhere to a principle that is only observed in its breach.
But setting that aside - under the doctrines of "R2P" (so beloved by Dick Cheney's cousin Barry, whom you evoked in your meme) and mutual assistance - Russia is obliged to intervene in the Ukrainian Civil War, raging since 2014, and right on their border - given the obvious failures of the Ukrainian side to honor their commitments under the Minsk Accords. They could not stand by, and watch that slaughter continue, forever. And the presence of 12 (minimum) CIA Bases, and countless NATO BioWeapons labs, on their border
