is suspicious of the story about Donald Trump's interest in using nuclear bombs to solve America's foreign policy problems. It looks like a rumour repeated on national television. I don't always trust Snopes on politics, so by all means show me where you go for checking on things.
I think a most favourable interpretation, if the story is true as told, is that Mr. Trump accepted that nukes don't solve all the problems, but wanted to have it explained to him in detail why some particular cases weren't nukable at this time, and what would have to change so that they are.
