Realistically the americans lost in those wars because the presidents at the time actually wanted some kind of spiritual victory rather than just flattening those countries into dust with sustained carpet bombing of any and all artificial structures (At least not the whole country) I doubt Trump would have any issues or even understanding of the consiquences of going full nuclear. The US likely wouldn't surive the retaliation but neither would anyone else... except New Zealand because everyone forgets them so hard they even get left off maps.
