If it’s true that politicians generally honor their foreign policy campaign pledges, Trump isn’t interested in making very many specific commitments that might so constrain him. Having a list of foreign policy advisers would give the rest of us some clue what his policies would look like, and so perhaps it is also no accident that this list has not been forthcoming.
.. It means that Trump’s campaign will be at a constant disadvantage when debating foreign policy despite the many glaring flaws in Clinton’s own record. It also raises another warning flag that a Trump administration would be poorly-staffed and ill-prepared to govern, and you can guarantee that will be used against the GOP in the general election.
Clinton has a lousy record and accepts many dangerous assumptions about the U.S. role in the world, but there’s no question that she will be well-briefed and can speak the lingo that foreign policy professionals and pundits expect to hear. Trump isn’t and for the most part doesn’t. That may be an important part of what his supporters like about him, but it could also make him an easy target in general election debates. This isn’t a problem that’s going to fix itself, and it’s one of many things that the Trump campaign has to take a lot more seriously than it has.
