"Ending the Iraq war has allowed us to strike decisive blows against our enemies. From Pakistan to Yemen, al Qaeda operatives who remain are scrambling, knowing that they can't escape the reach of the United States of America," he said.
"From this position of strength, we have begun to wind down the war in Afghanistan. Ten thousand of our troops have come home and 23,000 more will leave by the end of this summer.
"This transition to Afghan lead will continue and we will build an enduring partnership with Afghanistan, so that it is never again a source of attacks against America," he said in his speech to the US Congress.Obama State of The Union Speech 2012 Video
Moments after he drive drown from White House to Capitol Hill, Obama told lawmakers that this generation of heroes has made the US safer and more respected around the world.
"For the first time in nine years, there are no Americans fighting in Iraq. For the first time in two decades, Osama bin Laden is not a threat to this country. Most of al Qaeda's top lieutenants have been defeated. Taliban's momentum has been broken, and some troops in Afghanistan have begun to come home," he said.
