I'd just like to get back to something: 'america is evil'
No country is either good or evil, they're not capabpe of it, the people of a country are generally pretty good, they kight be selfish or bigotted, but that will rarely make it's way into international policy (domestic policy may mean that a country of biggots is not one which you would like to migrate to)
Japan for example is rather xenophobic, it is one of the few 'developed' countries which isn't making up for low indigenous birth rates by external migration.
But when i talk about the US does this thing and i don't like it; that is not a reflection of the people or their intentions. Politically what the US (or other democracies) CAN do is limited by what the people think, so 'the powers that be' are limited to doing things quietly or justifying them with propoganda.
Individuals are able to make a difference - look a Bill Clinton as an example, he has talked about the difference between being an individual leading a crusade to make a difference on some specific issue and being president - where he did many things at once but never to the same degree; something else always needed to be done... Sure he could make sweeping long lasting policy changes; but they would always but limited by how they were implemented - whereas an individual can focus their entire career on the implementation of a specific thing.
So i might generalise, all individuals are capable of good/evil; all nations are amoral.
If you see a news piece talking about Iran, Russia, Venezuala or China; remember the nation may actually be corrupt, it may be acting against US interests (or whoever the propoganda you are watching is biased toward) it may be the they've done something actually 'wrong' by any legal definition - but laws are subject to change, international conventions are just vague agreements which are determined more or less on a might makes right basis - i would say that a country is right to do something which benefits it's citizens. That view would be one where countries exist to protect some subset of human population and that you consider this to be a good thing... The alternative view is that this is a bad thing. And both views are rather limited, there are really no absolutes, generally countires do both good and bad things to people.
As for the white terrorists; i'm not talling about white muslim extremeists in prison. I'm talking about anti-muslim, anti-jewish, anti-black/latino supremacists who use fear and terror for political ends - to 'keep america american' - this is terrorism by definition. They are essentially Nazis, and likely also filled with hate.
