BOB MCMANUS: Trouble Again at Sea: The collision of the USS John S. McCain is more evidence of a beleaguered Navy. “The idea that two Navy destroyers—the legendary greyhounds of the sea, lean, swift, and agile—could be run down and severely damaged by lumbering merchant vessels within two months is preposterously unlikely. Yet it has happened.”

Plus: “Considering the Navy’s current state, it should perhaps not be as surprising as it is. Today’s Navy has far fewer ships than it needs to carry out its assigned duties; its sailors are over-deployed and under-rested; its equipment is often obsolescent, and it is emerging from eight years under the leadership of a Navy secretary, Ray Mabus, whose social-justice priorities almost always took precedence over tradition, morale, training, and operational readiness.” Less of that, please.
