Is that some sort of gotcha? By all means, boycott those countries as well. Support from the US certainly is not a free pass.

Follow the logic and boycott the US as well! Now you have zero viable search engines

I have plenty of reservations about the US, but the invasion of the Ukraine is not in the same category as anything the US is up to.

So sure, you are.

Could you give an example of US actions that are comparable to the Russian invasion of Ukraine?

Support of Israel is as despicable (if not more so) as support of Russia.

Vietnam I agree with - but it would be weird to protest that now. The atomic bomb is more complicated and even weirder to protest now.

‘Middle East’ is a broad and also hard to compare. Lots of US policy I disagree with but is it like the Ukraine invasion?
