Each year at this time, we renew our resolve against those who perpetrated this barbaric act of terror and who continue to plot against us – for we will never waver in defense of this nation,” Obama said in the address. “We renew our commitment to our troops and all who serve to protect this country, and to their families. But we also renew the true spirit of that day. Not the human capacity for evil, but the human capacity for good. Not the desire to destroy, but the impulse to save.”
Obama, who is marking the anniversary with a visit to the Pentagon, also said, “On this day, we recall that at our darkest moment, we summoned a sense of unity and common purpose. “
“We responded to the worst kind of depravity with the best of our humanity,” he added.
