To let the American public get updates to the President's speech via SMS is dangerous and, presumably, equivalent to Al Qaeda and Taleban propaganda. No wait, those messages come through just fine so it must be worse than that and even Iranian, Russian, and Chinese Government propaganda. If you're an American, you cannot sign up for SMS updates to what surely will be an excellent speech by the President - nor could you sign up for the previous much anticipated and lauded speeches - because the Smith-Mundt Act prevents American public diplomacy activities from reaching sensitive and impressionable American eyes and ears. If you're in the 50 United States ("US minor outlying islands" don't count) then you'll have to hope the State Department's Public Affairs
does something, but, call me a pessimist, I wouldn't hold your breath.
