By "coup" you are referring to the almost million Ukrainians that came out to protest? If so, then no, its not a coup it is the will of the people.
In theoretical ideal, yes, but in the reality of realpolitik, not so much.
North Korea isn't a good example, but think of a nation like the U.S. We wouldn't let the Soviet Union build missile bases a few miles from our border. Regardless of what the Cubans think, or their theoretical right to engage in military commitments with any nation they choose. The Russians likewise have deep antipathy toward NATO being on their border, and a willingness to kill people to prevent it.
Putin severely misjudged Russia's military strength vis-à-vis Ukraine and those willing to help her. But he took these actions in light of the final neocon push under the Biden administration to pull Ukraine into the NATO orbit.
The September 2021 joint statement provoked Russia's last bid at a diplomatic settlement of the question. When the Biden administration told them in December of 2021 to 'pound sand' I think Putin resolved at that point he'd have to pound Ukraine instead until they recommitted to neutrality.
After the 2014 coup in Ukraine led to the civil war Ambassador Burns predicted in his 2008 cable to the Bush White House, I charitably thought the neocons had simply misjudged where Russia stood on the subject. But after the 2021 decisions, it was clear to me they wanted Russia to start a shooting war.
Don’t compare America and European free nations to Putin the 26 year strong man dictator of Russia, Kim Jong Un of Communist North Korea, XI of Communist Red China and Iran, who are ALL part of this invasion.
Russia hates countries protecting themselves from Russia because Russia wants to conquer them, and many, many cases Reconquer, NATO and Russia are not just two sides of the same coin, where do you guys come up with that bizarre view of the world’s enemy nations?
Russia and North Korea are invading a free country in Europe, and Red China is training the Russian troops, there is no justification, zero.
Quit supporting Russia, North Korea, Red China, and Iran, against our side.
Ukraine had agreed to neutrality, but it was Russian maximalist demands such as Ukraine's complete disarmament, "denazification" - code for restructuring Ukraine's political leadership and limiting its national sovereignty, recognition of Russian language on par with Ukrainian, etc. which ended negotiations in Istanbul.
