In the 21st century, the US has inserted it's military into Libya, Yemen, Syria, Iraq, Uganda, Somalia, Northeastern Kenya, Pakistan, and our war in Afghanistan is old enough to be starting college soon. Does the world really need Trump at the helm ? We have lost the ability to assure the world that we are not going to put a sociopath in charge of this mess and maybe even double down on keeping him. That's probably another question we should consider when we decide if we should stay or go.
Oh certainly, and the fact that Trump is spectacularly ill-suited for the role of C-i-C of US forces should be sufficient to dissuade people from voting for him, though obviously it isn't enough, unfortunately, any more than the incompetence and lack of ability that he brings to almost every other aspect of the job, other than signing stuff for the cameras when he's reminded to, seems to worry them.
However, the question of whether a particular candidate is a good C-i-C or not is completely separate from whether it's advisable for the US to withdraw from any particular military conflict in which it's currently engaged, though that candidate's ability, if elected, to deliver a more or less successful withdrawal is another matter that needs consideration.
I'm guided in my thoughts about this by my country's experience of extracting itself from various colonial and post-colonial conflicts. While, as far as I'm concerned, the difficulties we experienced over the last 100 or so years should be sufficient to dissuade people from over-hasty action (as should the experiences of Korea and Vietnam still serve as a warning to Americans about getting involved in such wars), Britain's experience in NI demonstrated pretty conclusively that it's a lot easier to send troops in somewhere to prevent bad things happening than it is later to withdraw them without even worse things happening as a result.
Rudyard Kipling, for all the casual racism inherent in the imperial outlook, knew a thing or two about the complexities of colonial administration, and one of his more (in)famous poems on the subject, which is often misleading referred to by only its half title, is worth re-reading by both the politicians and citizens of the nation to which it was addressed:
The White Man's Burden — The United States and the Philippine Islands.
