"Calling" someone your enemy is completely useless when you're executing their foreign policy. If you care more about who they "call" their enemy rather than who they are actually murdering, then... Well I'll stop right here out of respect.

And this isn't even about Russia or China. ISIS was born out of the Syrian war, yet again executing someone's foreign policy. ISIS shared a border with Israel for a time and never made any attacks, but continue to murder Muslims time after time.
