What I "really believe" is that the US's role in supporting Maiden was about as meaningful as Russia's attempts to support their puppet in Kiev. This was not a coup. It was a revolution. Every revolution in history has been initiated and maintained by a relatively small cadre committed to that cause. Did the US have contact with the leaders of that anti-Russian pro-Western European movement? Of course we did. We don't need leaked conversation between Nuland and the ambassador to prove it. After all we were hardly secretive about it. Senators Murphy and McCain went to Kiev and McCain actually addressed the crowd.
While I subscribe to the notion Maidan was a revolutionary movement, it was not a Coup d'etat. It was the removal by a vote of the Parliament of a President who had reneged on his electoral program for obscure reasons, had ordered the police to brutally repress what was initially a peaceful protest, and finally had fled the country. What the conspiracists conveniently overlook is that Yanukovych was removed by a large majority of the Parliament, including members of his own party, which then organized new democratic elections as soon as possible—hardly the outcome or events associated with a putsch or they?
But in this country, it is far easier to believe in the machinations of an evil and corrupt intelligence service than the expression of the will of a people wanting to be free of Russian domination.
Did Russia attempt to halt that revolution? Of course they did. But because it was an expression of the popular will of the Ukrainian people, the Russian efforts failed - not because the CIA out maneuvered them. The Kremlin then reverted to type by actively supporting an insurgency in the Donbas and seized Crimea.
Where I think we are likely in some agreement is the point this needed to be resolved was in 2014 through very tough negotiations between the US/NATO/EU/Ukraine and Russia. Perhaps a deal with teeth could have been negotiated. It likely would have been far from perfect, but I am certain it would be better than where we are right now. Putin might just agree as he stares at the NATO border almost visible from the Winter Palace. But like all of this discussion that was then, and not now.
Finally, I believe that assumption is nonsense unless the "huge swaths" are the Donbas and Crimea. And even in the Donbas the approval rating of the independence vote of 1991 was 80-85%. No, that is not a survey of attitudes at the time of Maidan, but it does indicate a "huge swath" of commitment to independence from Russia deeply held by the vast majority of the Ukrainian people. Again, I simply point to the actions of parliament 2014 and the enthusiastic participation in and results of the following election. Since 2022 they have demonstrated that commitment in a far more profound way.
