If I believed that Clinton was going to start World War III, and that Trump would stop it, then I would vote for Trump despite all of his nastiness.

In reality, I believe Trump is much more likely to start WWIII, which is yet another reason to be opposed to him, but it is extremely uncharitable to assume that all of his supporters support everything that he does. I think most Republican voters simply believe he's the lessor of two evils. I strongly disagree with them, but respect the democratic process.

I think Clinton and Trump would each start WW3 in different ways, which makes it harder to directly compare. He would do something stupid/impulsive which couldn't be walked back (most things can, thankfully), or would cripple long-term alliances making war more likely later. She would get involved in some situation (no one thinks Trump is competent enough to let him actually engage in an intentional expansion of a conflict), which then escalates out of control.

I completely agree that being a single-issue voter on "preventing WW3" is the most moral thing possible. It's just really hard to tell which is less likely. And maybe if it is 0.00000001% vs. 0.000000011%, some other issue should have priority.
