America is not a single entity, and what you attributing to them isn't even a representative of the opinion of a majority of Americans (whom don't have equal democratic representation in the US government).

As I said in another comment here, the Bush administration's invasion of Iraq sparked one of the biggest protests in modern history and Bush would leave office as the least popular president since they started keeping track of public opinion. There is still a lot of injustice in the US, and everywhere you find it you also find Americans fighting against it as well.

We all have a couple of options here. We can make the Russian invasion of Ukraine about the US and it's ongoing fight against it's own injustices or just accept that Americans are highly valuable allies needed to help stop Russia in its tracks and talk about that, and leave the discussion of US politics to the politics subreddit.
