 There's no telling what's going to happen with the USA and Israel's apparently successful installation of Al Qaeda as the government of Syria.  And it's hard not to see this as a "win" for the dementia-addled US empire.  (There HAD to be a relative decline of US power after its artificial pre-eminence in 1945, but it's clear that at present, the USA has become a hollowed-out financialized economy dominated by gouging oligopolists with the living standards and life expectancies of ordinary citizens declining.)  All of this dangerous lashing out by the USA and Israel is a sign of weakness.  Assad of Syria was weaker.  But that had always been the case.

But what about the supposedly rising powers of Russia and China and their supposed "unlimited partnership" that makes a whole that is greater that the mighty sum of its parts?

Perhaps Russia and China (and Iran) realize that they're only going to get stronger as the years pass.  Whereas (as the clear decline of Europe, and the hell-holes that Iraq, Afghanistan and Libya became after US-American "victories", and the nightmare of Latin America under US-American domination demonstrates) the USA will only get weaker, ... perhaps they're prepared to sacrifice Syria, Hezbollah and the Palestinians.  

Why should they respond to this dubious "success" with a war that nobody wants and which (in the case of Iran anyway) invite total destruction?  The USA will do enough to destroy itself without either of those powers doing anything to help that along.  And, also, it's entirely possible that the brainiacs in charge of US foreign policy underestimate the dangers of a shit-head Sunni-fundamentalist government in Damascus.  There is going to be chaos and it might also be the case that (in the years since the "Rules-based International Order" has been harassing China and Russia, that those two countries have been coordinating their responses.  And they can afford to play a long game.
