Bret Stephens:

On Dec. 16, 1907, the 16 battleships of the U.S. Atlantic Fleet sailed from Hampton Roads, Va., on a 43,000-mile journey around the world. The occasion was immediately understood as Teddy Roosevelt’s way of declaring that the United States, already an economic superpower, was also a military one. Unnoticed by most Americans, this past Sunday marked its centennial.

There is an enduring, bipartisan strain in American politics (think Ron Paul and Dennis Kucinich) that wishes to forgo the military role. As wonderfully recounted by Jim Rasenberger in “America 1908,” the voyage of the Great White Fleet, as it was popularly known, was energetically opposed by members of Congress, who sought to cut off its funding when it was halfway around the world. Sound familiar? Mark Twain considered the venture as further evidence that TR was “clearly insane . . . and insanest upon war and its supreme glories.”

In fact, Roosevelt had sound strategic reasons for putting the fleet to sea. A year earlier, the British had commissioned their revolutionary Dreadnought battleship, setting off an arms race with Germany that helped set Europe on a course to World War I. Labor riots against Japanese immigrants in California had strained relations with Japan, whose dramatic naval victory over Russia at the battle of Tsushima had made the rest of the world keenly aware of this rising Asian power.
