President Obama is working on a new nuclear strategy that will reverse some policies of the Bush administration, The New York Times reports. Obama will likely cut the American arsenal by thousands of weapons, but he has yet to decide the country’s position on when to deploy nukes, an issue that’s been hotly debated within the administration as it prepares the Nuclear Policy Review. The new policy will call for no new nuclear weapons, and push for the development of non-nuclear alternatives and a greater reliance on missile defense. And tactical nukes could be removed from Europe. Some critics say Obama is naïve to commit to the anti-nuclear weapons movement as nations like North Korea and Iran move toward developing them, while others worry the president won’t change current policy that allows for a nuclear response to a chemical or biological attack.
