WASHINGTON (AP) - Delaying what had loomed as an imminent strike, President Barack Obama abruptly announced Saturday he will seek congressional approval before launching any military action meant to punish Syria for its alleged use of chemical weapons in an attack that killed hundreds.
With Navy ships on standby in the Mediterranean Sea ready to launch their cruise missiles, Obama said he had decided the United States should take military action and that he believes that as commander in chief, he has "the authority to carry out this military action without specific congressional authorization."
At the same time, he said, "I know that the country will be stronger if we take this course and our actions will be even more effective." His remarks were televised live in the United States as well as on Syrian state television with translation.
Congress is scheduled to return from a summer vacation on Sept. 9, and in anticipation of the coming debate, Obama challenged lawmakers to consider "What message will we sent if a dictator can gas hundreds of children to death in plain sight and pay no price."
The president didn't say so, but his strategy carries enormous risks to his and the nation's credibility, which the administration has argued forcefully is on the line in Syria. Obama long ago said the use of chemical weapons was a "red line" that Syrian President Bashar Assad would not be allowed to cross with impunity.
Nor was it clear what options would be open to the president if he fails to win the backing of the House and Senate for the military measures he has threatened.
Only this week, British Prime Minister David Cameron suffered a humiliating defeat when the House of Commons refused to support his call for military action against Syria.
Either way, the developments marked a stunning turn in an episode in which Obama has struggled to gain international support for a strike, while dozens of lawmakers at home urged him to seek their backing.
Halfway around the world, Syrians awoke Saturday to state television broadcasts of tanks, planes and other weapons of war, and troops training, all to a soundtrack of martial music. Assad's government blames rebels in the Aug. 21 attack, and has threatened retaliation if it is attacked.
Russian President Vladimir Putin, saying he was appealing to a Nobel Peace laureate rather than to a president, urged Obama to reconsider. A group that monitors casualties in the long Syrian civil war challenged the United States to substantiate its claim that 1,429 died in a chemical weapons attack, including more than 400 children.
By accident or design, the new timetable gives time for U.N. inspectors to receive lab results from the samples they took during four days in Damascus, and to compile a final report. After leaving Syria overnight, the inspection team arrived in Rotterdam a few hours before Obama spoke.
The group's leader was expected to brief Secretary-General Ban Ki-moon on Sunday.
Republicans generally expressed satisfaction at Obama's decision, and challenged him to make his case to the public and lawmakers alike that American power should be used to punish Assad.
"We are glad the president is seeking authorization for any military action in Syria in response to serious, substantive questions being raised," House Speaker John Boehner of Ohio and other House Republican leaders said in a joint statement.
"In consultation with the president, we expect the House to consider a measure the week of September 9th. This provides the president time to make his case to Congress and the American people."
There was one dissenting view, from Rep. Peter King., R-N.Y. "President Obama is abdicating his responsibility as commander in chief and undermining the authority of future presidents," he said. "The president doesn't need 535 Members of Congress to enforce his own red line."
Senior administration officials said Obama told aides on Friday night that he had changed his mind about ordering a strike against Syria without seeking congressional approval first, making a final decision after a long discussion with his chief of staff Denis McDonough.
It was unclear what pressure Republican or Democratic lawmakers had brought on Obama.
For now, it appeared that the administration's effort at persuasion was already well underway.
The administration plunged into a series of weekend briefings for lawmakers, both classified and unclassified, and Obama challenged lawmakers to consider "what message will we send to a dictator" if he is allowed to kill hundreds of children with chemical weapons without suffering any retaliation.
At the same time, a senior State Department official said Secretary of State John Kerry spoke with Syrian Opposition Coalition President Ahmed Assi al-Jarba to underscore Obama's commitment to holding the Assad government accountable for the Aug. 21 attack.
While lawmakers are scheduled to return to work Sept. 9, officials said it was possible the Senate might come back to session
