He said the ethical thing to do would be to criticize the US, but also criticize the governments the US doesn't like for balance.

I had a look at this fellow's work online and did indeed see articles sharply criticizing China and Russia, as well as much weaker governments like Sri Lanka, the Philippines, and the Taliban. 

But guess what government I didn't see in his crosshairs?

This to me is the worst kind of moral cowardice. To live in Australia (effectively a member state of the US empire) and yet spend all your time criticizing far weaker and far less destructive governments than the US is like living in a Nazi-occupied territory during World War Two and spending your time shaking your fist at Brazil. It's like tut-tutting judgmentally when you hear your neighbor raise her voice at her kids even as you yourself are busy murdering your entire family with an axe.
