Any new economic sanctions that Congress tries to impose against Iran during international negotiations to limit the Islamic republic's nuclear program will be vetoed, President Barack Obama warned lawmakers on Tuesday, even as he acknowledged the ongoing talks are difficult and may not succeed.
It was the sharpest part of a State of the Union speech that overall was skimpy on details for his foreign policy agenda for the year.
Obama also briefly re-affirmed his promises to end the war in Afghanistan this year, pursue al-Qaeda with limited strikes and support Syrian opposition groups in their bloody three-year quest to push their ruler from power. But he avoided clarifying some sticky key issues, including how many -- if any -- troops might remain in Afghanistan beyond December, or how he will try to convince Americans and foreigners alike that the National Security Agency is not snooping into their telephone and Internet records.
