What If World War III Happened Tomorrow?

Human history has been full of battles and wars, some big and some small. But if World War 3 were to happen, it might be humanity's biggest battle yet. Advanced technology, massive troops, and more intensive strategy would all be involved. Why would something like this happen? And how would this war be fought?
