The US is at the center of a vast network of multilateral international relations which, even as its individual position diminishes, would continue to exert considerable world influence. Just as did the British long after their empire and with declining GDP.

As for "waking up", it appears at the moment the decline is not creating a call for clear thinkers and rational solutions but for charismatic leaders who make Ghost Dance variety promises.
