P1. WW3 has already been lost! Lost not by US but by those who profited from it! And it did not end in THE END. Russia is afraid of losing its ability to play one side against the other in the ME. Israel has made it clear to Putin that it cannot afford the Status Quo any longer ( it is causing too much internal and international damage ). Russia depends on Israel's good will! Yes! Surprised? It's simple: Russia needs Israel's approval to sell stuff to the EU. The EU is sick & tired of the serious negative economic impact of a Status Quo ME.
P2. The EU wants Russia to stop supporting the Iranian Regime and its proxies. The majority of the OPEC nations...meaning: the Arab Gulf States, Saudi Arabia, etc., are fed up with the Status Quo, because it is harming their longterm economic interests. And they also are sick & tired of the Extreme Shia Iranian Regime's threat & harm to Sunnis. The Chinese want World Peace badly: their economy is about to implode, UNLESS Peace Prevails in the ME & elsewhere.
P3. The Chinese own a huge share of the USA's debt! IF the USA-EU economic bridge is not strengthened then China will face disaster! The Iranian Regime is actually crumbling within! The Iranian people are wisening-up and are also disgusted by their Regime's support for Assad: even as they fear for their fellow Shia minority in Syria. The USA, EU and the Arab OPEC nations want to insure that the Syrian Shia & Christian minority will have a separate part of a divided Syria ( for the sake of peace).
