Surely you realize it's absurd to suggest Russia will put 150,000 troops in Syria...and that the Chinese will put 8,000...right?
I know there have been false reports posted on this forum suggesting that.
But nothing from anyone that could be considered reputable.
China will not deploy ANY combat troops to Syria and Russia would have a hard time supporting 40,000.
And if you think Russia will attack a country with 200+ deliverable nukes, you're crazy.
China has significant oilfields there. They abandoned them when fighting broke out. There are also Eighurs fighting there who will return to china and spread discontent if not killed first. Plus they have new troops, aircraft & an aircraft carrier that need real wartime experience. It is a conflict with little downside for them. No enemy aircraft, no enemy intel or large armor forces. No real threats to their only working carrier. A darn fine training opportunity.
You may not think they will go, but I say there is a good chance of it.
