Obama would veto new congressional sanctions bill on Iran

US President Barack Obama warned early Wednesday that he would veto any new sanctions bill passed by Congress against Iran. International negotiations on preventing Iran from developing a nuclear weapon “will be difficult and they may not succeed,” he said in his State of Union Address early Wednesday to a joint session of the Congress. But “For the sake of our national security, we must give diplomacy a chance to succeed.”
Also in the foreign section of his address, Obama said, "A small force of Americans could remain in Afghanistan with NATO allies" after 2014, if the Afghan government signs a security agreement. (The “if” refers to Afghan president Hamid Karzai”s refusal to sign one.) The post-withdrawal mission would involve training and assisting Afghan forces as well as continuing counterterrorism operations against "remnants of Al Qaeda", the US President said, adding he had imposed prudent limits on the use of drones."
