Barack Obama's Vision of Nuclear Nonproliferation Won't Deter Tehran or Pyongyang

The President went even further in Prague, noting that "as a nuclear power -- as the only nuclear power to have used a nuclear weapon -- the United States has a moral responsibility to act." That barely concealed apology for Hiroshima is an insult to the memory of Harry Truman, who saved a million lives by ending World War II without a bloody invasion of Japan. As for the persuasive power of "moral authority," we should have learned long ago that the concept has no meaning in Pyongyang or Tehran, much less in the rocky hideouts of al Qaeda.

The truth is that Mr. Obama's nuclear vision has reality exactly backward. To the extent that the U.S. has maintained a large and credible nuclear arsenal, it has prevented war, defeated the Soviet Union, shored up our alliances and created an umbrella that persuaded other nations that they don't need a bomb to defend themselves.
