You you think there will be another World War?

Given the current situations we have at hand, In my own opinion, I think it's rather likely that we will see another World War, it's certainly impossible to predict when, and due to vagueness all that can be said is "in the near future". There are a myriad of problems or occurrences which could spark one, as you've seen in previous wars, some have started due to the assassination of a heir to a throne, some because of someone getting their ear cut off.

Due to the sporadic nature of these events, the ones that today on the modern day are more likely to cause something of such magnitude, could be

a) The dispute in the South China Sea
b) India vs Pakistan (old feud)
c) Ukraine
d) The Middle East in general

I will not dwell into the certain events which could procure these, it would take far too much space. When it comes to the more intriguing matter, is whether or not nuclear weapons could be used. Now, I think that every human leader knows what using one would and could entail and lead to, I don't think any would use one unless they're in dire circumstances (someone that'd use them for the fun of it would probably be Kim Jong-Un). I don't think every human is rational, nor do I believe the world is founded on compassion and all that hogwash, therefore due to the nature of when to use a nuclear device, is impossible to speculate on. Because there'd have to be a specific scenario given, I don't think they'd use them from the outset of war.
