Yes, because the US had one of the most effective propaganda machines of all times.
You know, participants of a war always believe their side is right and they’re fighting the good fight. Otherwise they wouldn’t do it. And while you’re certainly right that Putin shouldn’t be considered harmless, a victim or even an opponent with equally valid interests, it’s still naive to think the US is just defending against the Putins in the world.
That's how I see the United States and the old USSR, modern Russia and to a lesser extent, China (I tend to view China much more favorably than Russia). Does that mean the U.S. is perfect? Nope, we're not. Sometimes we're wrong and disastrously so. Does that mean every Russian is bad? Nope, I've worked alongside many awesome Russians over the decades. Some were even in the Russian Army at the same time I was in the Marine Corps and we've laughed that here we are now in a bar having a beer together whereas a few years before we would have been on a battlefield trying to kill one another.
In that regard I see Putin and Trump very similarly. Putin has reminded us that Russia hasn't advanced as much as we'd thought, and Trump showed us that our lesser selves were always there under the surface brewing and waiting for a monster such as him to release our demons and let them run amok. They're old-school people from whom the reigns of power should be taken away.
Everyone in the community, us kids included, considered this to be serious and vital work for defending the US from the USSR, an adversary who's brutality has been revealed for the umpteenth time in the Ukraine attack. I, for one, would like to see the US strive to actually live up to our stated ideals. Unfortunately, Reagan showed the neocons all you have to do is act like you care about your ideals.
WRT your link - that video was obtained via a FOIA request. Do you think Putin would allow such a video to be released? Yeah, we're not perfect but at least we're still allowed to talk about the bad things we do, openly gripe about our government, and demand more accountability. THAT is something for which US citizens can still be envied.
