[@LeeRoy] 'World War 3' would, by definition, have to involve at least a significant chunk of the rest of the world.

The Rest Of The World doesn't really care about Hillary.  She may be an aggravating battleax, but...well, she's fundamentally not much different than anything that's come before her.

Trump?  Trump is [i]actively campaigning on the "I'm a racist fuck" platform[/i].  He alternatively (or simultaneously!) terrifies and infuriates the rest of the world - the mere fact that he has anything resembling a chance has, [i]itself[/i], already damaged what's left of America's international standing.  He's an aggressive, provably amoral businessman who is, so far as I can tell, doing this pretty much for the kicks rather than out of any real desire to try and improve the country.

if I were to pin the "Most Likely to start World War 3" yearbook award on any of the current candidates, it would not be Hillary.
