Well diplomacy is built on quid pro quos and whataboutism so I don’t know what’s childish in this, if anything this comment comes off as pretty naive and childish.
I'm sorry, but no, that is not diplomacy. If you think that is diplomacy, then you're spending a lot of time on tabloids and news headlines and no time where the diplomacy is primarily happening: in stuffy meeting rooms.
This is the behavior of actual children who can't stand to be subjected to critique and deflect with screams and shouts of their own victimhood.
Tomorrow it will be China's debt crisis, and the day after America's latest foreign intervention come to haunt them again but you know what? You can wait your turn. That's the very adult thing to do.
