When I think of America’s place in the world today, the image that comes to mind is of a very large animal, perhaps a huge bull elephant or even prehistoric mammoth, which long roamed as the unchallenged king of its domain but has become trapped by its own missteps, as caught in a tar pit or some quicksand, and it is violently flailing about, making a terrifying noises in its effort to free itself and re-establish its authority. Any observer immediately knows the animal ultimately cannot succeed but certainly is frightened by the noise and crashing that it can sustain for a considerable time.
