WATCH: President Trump says that he could win the 18-year Afghan War in 10 days, because he has plans that could wipe Afghanistan off the face of the Earth and kill 10,000,000 people, but "I don't want to go that route." pic.twitter.com/IftsRmBjpG— NBC News (@NBCNews) July 22, 2019
A lot of people would tend to doubt the diplomatic chops of someone who suggested they've given thought to ending a war by glassing 10 million people, but then decided it wasn't fair, and this is probably why India's government wasted no time in responding to the idea floated by Trump that he could mediate a resolution between that country and Pakistan regarding Kashmir to say, albeit more diplomatically, "like hell he will."
Which is really just as well. There are definite reasons to doubt his understanding of the political, geographic, and religious considerations involved in a meaningful dialogue, in addition to his undiplomatic personal tendencies. Even if he does think he might rather like a Nobel Prize someday.
