That was always going to be the case I think, given what we know about the power behind the scenes or "one world govt." It was 'easy' for Putin to stand up geopolitically to anglo-America over the past 15 years (most notably because it was at least good for his domestic reputation), but when something like 'the pandemic' was dropped on the world, he had no choice but to fall in line. He simply can't stand alone in that respect. There's another angle on this that, perhaps, makes Putin's stance more understandable, and it relates to the most important factor for any govt.: control over the local population.
As things progress and the overt control measures on populations become more extreme, there's a risk that more and more people will start to wake up (if only in an unthinking reactive way) and start to lose faith and obedience in domestic authorities. The 'pandemic' poses that kind of risk and, in the case of Russia with its possibly less naive population, perhaps a greater risk than elsewhere. So to avoid resistance to the 'pandemic' spreading throughout Russian society, and with it a general loss of faith in the domestic authorities, Putin may have decided he needed to push back against vax skepticism in an open and forthright way.
That's the best I can do to salvage some of his integrity, but I'm realistic enough to accept that, as Niall said, it's basically down to us and those that can See around the world. Forget about some relatively powerful opposing force from within the global governmental system(s). We're the 'opposing force', and again as Niall said we oppose by maintaining our free will, and we do that by continuing to learn and grow in Knowledge and Being, and being 'wise as serpents and gentle as doves'.
