I don't care if the US "invaded anyone for territorial expansion" or did it for shits'n'giggles. It has done all the above and more which weakens any chance that calls for democracy, international order, peace, stability and trade can work.
The US is deeply disruptive to any of that happening because it opens the door to the MiniMe despots being able to claim that spending stupid amounts of GDP on weapons and having a "strong leader" is the only thing which will see them safe from being invaded "not for territorial expansion" during a "long fucking time".
That's why it is appropriate, relevant and not simply whataboutism.
Russia and other states are worse than the USA because they need to be in order to claw their way up the dungheap piled up by US foreign policy. And there is little inherent in US norms or culture which would prevent similar anti-democratic and anti-liberal punishments. To back to the OP: these are all shades of authoritarianism and we see calls all over the media and this very forum in favor of censorship, war and other stupidities.
Don't kid yourself, this isn't whataboutism, it's the very subject under discussion: Russia is violating international agreements and norms and in part this is because the USA has shat all over those for a very long time.
