It may have been considered possible once, as the close of World War 2 did lead to the Cold War, which very nearlly turned into a Nuclear war.

Also if a Asian Communist nation was to start World war 3then that could be traced back to the Cold war and that in itself could be traced back to World war 2. It's all just a matter of perspective, for example; many causes of World war 2 have their roots in World war 1 so any war that could be traced back to the Cold war could then be blamed on events of World war 2 and in turn could be linked to the outcome of World war 1. So their is no yes or no answer as it really depends on how you look at it.
