Did you like forget that the primary duty of the President is to be Commander in Chief of the Armed Forces of the United States?
This stuff is really baffling to me. The president is allowed to fire nuclear missiles whenever he wants to! He controls all government action and most legislation through controlling the actions of the executive branch!
How do you look at the actions of Obama and George W. Bush before him and not recognize the vital importance of a capable and rational person in the Oval Office?
Of course this is true, but I also suspect, based on the picture of his personality that we've gotten from those who know them and on the campaign trail, that Trump is a paper tiger whose will will break when it comes to actually committing troops to some kind of ground war, because while he doesn't know what he's doing on any level of government, he REALLY doesn't know what he's doing when it comes to foreign policy, and knows and has public admitted it, and he's so thin-skinned and narcissistic, not to mention so much of a huge micromanager, that I don't think he'd risk the humiliation of running a disastrous Iraq-like war that he'd be beholden to his advisers to wage (and therefore have little direct control over, whatever his technical authority) and being tarred with that for a generation. And if there were an Afghanistan-like justified war that became necessary, I suspect there would be bipartisan outreach to actually get it done smartly, however little either party will desire to help Trump in day-to-day matters of governance.
Anyway, I don't disagree that you need a capable and rational person in the Oval Office, which is why I don't support Trump and will vote against him in November for the candidate best poised to beat him, despite not much caring for Hillary Clinton and preferring to vote Green. But I also think our government is smartly-constructed and has enough checks and balances on a multitude of levels to mitigate the damage even a demagogic assshole can do to it, especially if basically everybody else in the annals of power is aligned against him.
