Maybe. The US has probably done more evil than any other country in history, so it's easy to view it as "The Evil Empire". But it's only done so much evil because it's long been by far the most powerful country. If North Korea, Iran, or China were as powerful as the US, they'd do even more evil because they are built upon more evil ideologies, and they are more authoritarian. Unless you can somehow chart a very clear path between your actions and some wider utilitarian good, IMO it's not morally justifiable to help these oppressive regimes.

I'll be interested to see what this guy has to say for himself.
