President Obama said even as the United States is embroiled in wars in Afghanistan and Iraq, it is also working to reduce nuclear weapons stockpiles. Obama pointed to recent negotiations between Moscow and Washington on what he called "the farthest-reaching arms control treaty in nearly two decades."
Even though those negotiations have not been completed, the president said this diplomatic effort has strengthened efforts to deal with Iran and North Korea, two countries that have ignored international agreements to pursue nuclear weapons programs. Obama said both countries face increased isolation and stronger sanctions.
His statement comes as his administration is reportedly preparing to circulate a proposal for more stringent sanctions against Iran over its nuclear program. The president sent a clear warning to Iran's leaders that they face "growing consequences" if they continue to ignore international obligations.
