How World War III could play out?

These articles were pretty informing on the potential future of warfare in World War III. Also I seem to have noticed a trend in World Wars, it seems like in both world wars and potential wars in the future there have been new weapons introduced into the war. The first world war saw the introduction of chemical weapons, but they were not used in the second world war, at least not on notable documents or the public. But WWII did see the use of nuclear weapons towards the end. But knowing how close we've come to a nuclear war we've came before and we know the extent of the damage it could cause we likely won't use nuclear weapons at all in WWIII. But an entirely new weapon will be introduced if it happens. My money maybe on large scale thermobaric explosives or mass scaled emps that shut down entire defense systems and grids without having to use a nuclear weapon. Or in the worst case scenario....... Bio weapons.

But here are the articles if you're interested in reading them. So what do you think?

let see Donald Trump wins the presidency and declare war on every country

What makes you think that Donald Trump is any more or less likely to start a war when compared to other candidates such as Hilary Clinton?

I'm looking for another cold war more then anything else.
