President Obama announced Monday that he has instituted a new nuclear weapons policy. The new policy essentially says that the U.S. would pledge to never use nuclear weapons against non-nuclear countries even if they attacked America or American interests with biological or chemical weapons.
It eliminates much of the ambiguity that has deliberately existed in American nuclear policy since the opening days of the cold war. For the first time, the United States is explicitly committing not to use nuclear weapons against nonnuclear states that are in compliance with the Nuclear Nonproliferation Treaty, even if they attacked the United States with biological or chemical weapons or launched a crippling cyberattack.
Meanwhile, Obama has resigned himself to the reality of a nuclear Iran.
