The Secretary of State doesn't do much but travel the world going to dinners and parties and passing notes from the President. It's the world's most expensive courier service. If we gave the job to whom ever was Miss America at the time we would have countries like us much more.
But the State Department is supposed to be one of the two prongs of influence we have around the world, you know, the diplomatic and the military. If the diplomatic channel isn't working correctly you can end up employing the military when it might not normally be necessary.
