If you think things are bad now, then, brace yourself: it is about to get a whole lot worse. If you are alarmed at the speed with which the Trump administration has set about dismantling every institution of American government and every pillar of the international order, you must understand that this is not just the initial burst of activity, the “shock and awe” phase after which things will settle down: if anything, the pace will continue to accelerate.
The world has never before been faced with such a threat. The United States has handed the nuclear codes to a madman, a criminal, a would-be dictator and a moron, all in the same person. Whatever the purpose to which he directs these powers – to impress his dictator friends, to further enrich himself and his cronies, to seize absolute power or just to watch the world burn – we must hope for the best, but prepare for the worst.
The other data point that’s useful is that, in the Continental Congress and in the political debates that led to the writing of the Constitution, there were constant complaints (mainly from the southern states) that northern states were negligent in maintaining the readiness of their militias. After the Constitution was written, this continued, and was one of the main reasons that US military leadership was predominantly southern: they got early military experience in their state militias.
