> Answer: Because on the whole it's not important enough to them to warrant the investment of effort and time. Because America's behaviors aren't that far out of the international norm of today (sad to say).

And to elaborate on “important enough” it’s about how beneficial for them is this to take the fight, and not about the moral or how "far out of the international norm". X can be amoral, but if powerful country X is doing it I will loose a lot in this fight, so I won’t take it. But if less powerful country Y is doing the same, there is high chance of winning and I will take the fight.

Asking “How about X?” is highlighting the issue - the more powerful country you are the more amoral things world can tolerate you doing. (The author of the comment doesn’t try to justify the bad actions, but tries to highlight the inequality of treatment).
