GOP senators press Obama on missile defense

“Not having to worry about the judgment of the American people on this important national security issue may allow more flexibility to make concessions to the Russians, but it would be antithetical to our safety and security and would be counter to other assurances you’ve given,” the senators wrote.

The senators warned that agreements limiting the speed and range of U.S. missile defense systems would go against assurances Obama made when the New START treaty with Russia was ratified in 2010.

They also pressed Obama about a provision in the National Defense Authorization Act that placed limitations on sharing missile defense information with Russia.

“We caution that any attempt to treat this provision as non-binding, as you claimed in your signing statement, could have serious repercussions,” they wrote.
