I’m glad we didn’t go to war but I don’t think this is some sort of accomplishment that the career leaders of one of the most notoriously trigger-happy militaries in the world did everything in their power to avoid a war while he was at the helm. If anything I think it’s an indictment of his incompetence as commander in chief.
Generals are on record saying that they would lie to Trump to keep troops in the ME. Trump would give the military deadlines to win or get out of the ME, and they would always beg for an extension.
If anyone talked Trump out of starting a war, it was Tucker Carlson vis-a-vis Iran. Trump did have a bone to pick with Iran, but he did pretty much nothing except kill Rouhani (want to compare that with I'm-pretty-good-at-this-killing-business Obama's kill list?)
