Specifically, the US federal government. Just like most Americans don’t hate the people of Russia or Iran any more than the folks the next town over, I’ve never met someone from Iran, Afghanistan, Syria, Pakistan, or pretty much anywhere else who hates all Americans. I’m sure they exist, but probably as a small minority. There’s plenty of reason to hate our government though, especially if it has threatened to destroy your entire civilization.

Yeah, buy Americans are not target of Russian aggression and violence. Russia is kinda abstract ennemy far away. Feelings get stronger when the country is actual target of bombing.

Growing up in the Southern US, I met plenty "Let's bomb all the savages in the Middle Easy and take their oil" types. Some of them grew up to be self-proclaimed Nazis.
