Killing the Amazon is a crime. Nothing done in the US or anywhere else changes that, regardless of whether that was a crime, too.

It is also not hypocritical unless you personally cut down a tree, or unless you believe in the collective responsibility of nations. I don't think 'the Brazialians' are responsible for killing the Amazon -- it's probably a minority of people and we shouldn't care which nation they belong too. This is a serious global problem, and it accidentally happens in some country. Neither collective blame nor collective shame will help. This problem must be criticised.
