I think there's also a failure to grasp that, although Trump is no-one's idea of a diplomat or genius, it is still possible for his administration to achieve foreign policy coups. Because when you are the biggest economy and most powerful military on earth, you don't actually have to be a genius to get results. You just have to be prepared to use the leverage those two statuses give you. Most US Presidents have been afraid to do this when it comes to the Chinese.
Essentially, yes. The tendency of really clever people is to overcomplicate things, empathise too much and try and think 20 moves ahead. They lose sight of their goals. They will try to untie the Gordian knot, when what it really needs is simply a swift sword stroke.
Trump's approach is to look at what the US wants, look at what cards it has to play and play them.
