Indeed, Obama’s dismissal of Russia as a regional power makes his own leadership of the one superpower all the more embarrassing. For seven decades since the Japanese surrender, our role under 11 presidents had been as offshore balancer protecting smaller allies from potential regional hegemons.

What are the allies thinking now? Japan, South Korea, Taiwan, the Philippines and other Pacific Rim friends are wondering where this America will be as China expands its reach and claims. The Gulf states are near panic as they see the United States playacting nuclear negotiations with Iran that, at best, will leave their mortal Shiite enemy just weeks away from the bomb.

America never sought the role that history gave it after World War II to bear unbidden burdens “to assure the survival and the success of liberty,” as movingly described by John Kennedy. We have an appropriate aversion to the stark fact that the alternative to U.S. leadership is either global chaos or dominance by the likes of China, Russia and Iran.

But Obama doesn’t even seem to recognize this truth.
