obama keeping america safe while destroying countries like yemen, libya, Afghanistan, poki-stan etc.. saved america from going into a depression, saved the country from going into ww3 with an unknown alien civilization from another planet. protected us from natural disasters that wrecked havoc in japan and other parts of the world. we owe so much to the president. do we not?
