While our land forces are for unpredictable contingencies, our sea and air forces secure the global commons. The navy is our away team: its operations tempo around the world is the same, whether in peacetime or wartime. So crucial is our navy that were just one of America's eleven aircraft carriers sunk or disabled by an enemy combatant, it would constitute a national disaster in strategic and reputational terms as devastating as 9/11. Manifest Destiny, the conquest of a continent with its unleashing of vast economic wealth and national will, reaches a point of concision here at Naval Base San Diego. It is a fitting end to my journey.
