This is the latest indication that the US is switching to Ukraine as the locale to start World War III, and from which the nuclear war is to be sparked against Russia, which borders Ukraine. 

Here is why Syria is no longer the US alliance's preferred choice as a place to start WW III:

On September 4th, US President Donald Trump publicly threatened Syria, Iran and Russia that if they exterminated the jihadists in Syria's only remaining jihadist-controlled province, Idlib, then the US might launch a full-scale invasion against Syria, Iran and Russia in Syria. Either the US or Russia would then quickly escalate to nuclear war so as not to lose in Syria — that would be the conventional-war start to World War III.
