The problem is, he will probably get his conflict, but things may spiral quickly out of control as China and Russia join the conflict on the side of Iran, or simply the side of HELL NO AMERICA.
I don't see it getting that far.
Russia and China are not in Syria and Iran to star a war and side with 'em, they are there to prevent a war and gain control of the oil and gas in the region.
Currently, Iran's oil goes to Western Europe in competition with Russia (same was true for Libyan oil). Redirect that oil to China and China's economy has a major uptick and Russia has Western Europe by the balls.
Russia will protect Israel to PREVENT a war and continue the instability of the region.
