During the run-up to World War II, Winston Churchill, speaking in Parliament, lamented “the years that the locusts hath eaten” – the period during which preparatory action to face the great crisis of his day (the rise of Continental fascism) could have been taken, but was not. Over the past century – with the notable exception of the Great Depression – the US political system has been remarkably good at foreseeing crises long before they have happened, and at least setting the foundation for dealing with them when they have occurred.
