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.
I agree that a full scale war against the US military using small arms is probably not likely to go well for those attempting it, but assassinating a president is a different thing altogether. America has assassinated many presidents.
