Iran's hard-line president has ridiculed President Barack Obama's new strategy aimed at reducing the likelihood of nuclear conflict.
Obama on Tuesday announced new rules constraining the use of America's nuclear arsenal, vowing not use nuclear weapons against countries that do not have them. However, Iran and North Korea were not included in that pledge because they do not cooperate with other countries on nonproliferation standards.
Iranian President Mahmoud Ahmadinejad, addressing thousands in northwestern Iran on Wednesday, likened Obama to a "cowboy" and called him an inexperienced newcomer who follows the will of Israel. Ahmadinejad said the U.S. president "can't do a damn thing."
