Obama: Syria 'Atrocity' Must Have ResponseWASHINGTON DC — U.S. President Barack Obama says he has decided the United States should take military action against the Syrian government, for its alleged chemical weapons attack. Speaking to the nation Saturday at the White House, Mr. Obama said this would not be an open-ended intervention and will not include U.S. troops on the ground in Syria. Obama said the U.S. operation would be limited in scope and duration. The president also said no military action will begin until and unless his plan is authorized by the Congress. President Obama said an "atrocity" with chemical weapons must not just be investigated but also confronted. He said the United States can not and must not "turn a blind eye to what happened in Damascus." He also urged members of Congress to consider that some things are more important than "partisan differences" as they consider the U.S. response to Syria.
