The most important question George W. Bush will face in his second term is whether he can follow Bismarck's example. If he can shift from shock and awe to the reassurance--and the attention to detail--that is necessary to sustain any new system, then the prospects for his post-September 11 grand strategy could compare favorably to Bismarck's accomplishments, as well as to those of U.S. presidents from Roosevelt through Clinton. For their post-Pearl Harbor grand strategy, over more than half a century, persuaded the world that it was better off with the United States as its dominant power than with anyone else. Bush must now do the same.
