WASHINGTON - Edging toward a punitive strike against Syria, President Barack Obama said Friday he is weighing "limited and narrow" action as the administration bluntly accused Bashar Assad's government of launching a chemical weapons attack that killed at least 1,429 people -- far more than previous estimates -- including more than 400 children.
No "boots on the ground," Obama said, seeking to reassure Americans weary after a decade of war in Iraq and Afghanistan.
With France as his only major public ally, Obama told reporters he has a strong preference for multilateral action. He added, "Frankly, part of the challenge we end up with here is a lot of people think something should be done but nobody wants to do it."
Halfway around the world, U.S. warships were in place in the Mediterranean Sea. They carried cruise missiles, long a first-line weapon of choice for presidents because they can find a target hundreds of miles distant without need of air cover or troops on the ground.
In what appeared increasingly like the pre-attack endgame, U.N. personnel dispatched to Syria carried out a fourth and final day of inspection as they sought to determine precisely what happened in last week's attack. The international contingent arranged to depart on Saturday and head to laboratories in Europe with the samples they have collected.
Video said to be taken at the scene shows victims writhing in pain, twitching and exhibiting other symptoms associated with exposure to nerve agents. The videos distributed by activists to support their claims of a chemical attack were consistent with Associated Press reporting of shelling in the suburbs of Damascus at the time, though it was not known if the victims had died from a poisonous gas attack.
The Syrian government said administration claims were "flagrant lies" akin to faulty Bush administration assertions before the Iraq invasion that Saddam Hussein had weapons of mass destruction. A Foreign Ministry statement read on state TV said that "under the pretext of protecting the Syrian people, they are making a case for an aggression that will kill hundreds of innocent Syrian civilians."
Residents of Damascus stocked up on food and other necessities in anticipation of strikes, with no evident sign of panic. One man, 42-year-old Talal Dowayih, said: "I am not afraid from the Western threats to Syria; they created the chemical issue as a pretext for intervention, and they are trying to hit Syria for the sake of Israel."
Obama met with his national security aides at the White House and then with diplomats from Baltic countries, saying he has not yet made a final decision on a response to the attack.
But the administration did nothing to discourage the predictions that he would act -- and soon. It was an impression heightened both by strongly worded remarks from Secretary of State John Kerry and the release of an unclassified intelligence assessment that cited "high confidence" that the Syrian government carried out the attack.
In addition to the dead, the assessment reported that about 3,600 patients "displaying symptoms consistent with nerve agent exposure" were seen at Damascus-area hospitals after the attack. To that, Kerry added that "a senior regime official who knew about the attack confirmed that chemical weapons were used by the regime, reviewed the impact and actually was afraid they would be discovered." He added for emphasis: "We know this."
The assessment did not explain its unexpectedly large casualty count, far in excess of an estimate from Doctors Without Borders. Not surprisingly -- given the nature of the disclosure -- it also did not say expressly how the United States knew what one Syrian official had allegedly said to another.
Mindful of public opinion, Kerry urged Americans to read the four-page assessment for themselves. He referred to Iraq -- when Bush administration assurances that weapons of mass destruction were present proved false, and a U.S. invasion led to a long, deadly war. Kerry said this time it will be different.
"We will not repeat that moment," he said.
Citing an imperative to act, the nation's top diplomat said "it is directly related to our credibility and whether countries still believe the United States when it says something. They are watching to see if Syria can get away with it because then maybe they, too, can put the world at greater risk."
The president said firmly that the attack "threatens our national security interest by violating well-established international norms."
While Obama was having trouble enlisting foreign support, French President Francois Hollande was an exception. The two men spoke by phone, then Hollande issued a statement saying they had "agreed that the international community cannot tolerate the use of chemical weapons, that it must hold the Syrian regime responsible and send a strong message to denounce the use of (such) arms."
The day's events produced sharply differing responses from members of Congress -- and that was just the Republicans.
Sens. John McCain of Arizona and Lindsey Graham of South Carolina said Obama needed to go further than he seems planning. "The goal of military action should be to shift the balance of power on the battlefield against Assad and his forces," they said in a statement.
But a spokesman for House Speaker John Boehner, Brendan Buck, said if the president believes in a military response to Syria, "it is his responsibility to explain to Congress and the American people the objectives, strategy, and legal basis for any potential action."
The looming confrontation is the latest outgrowth of a civil war in which Assad has tenaciously -- and brutally -- clung to power. An estimated 100,000 civilians have been killed in more than two years, many of them from attacks by the Syrian government on its own citizens.
Obama has long been wary of U.S. military involvement in the struggle, as he has been with turbulent events elsewhere during the so-called Arab Spring. In this case, reluctance stems in part from recognition that while Assad has ties to Iran and the Lebanese militant group Hezbollah, the rebels seeking to topple him have connections with al-Qaida terrorist groups.
Still, Obama declared more than a year ago that the use of chemical weapons would amount to a "red line" that Assad should not cross. And Obama approved the shipment of small weapons and ammunition to the Syrian rebels after an earlier reported chemical weapons attack, although there is little sign that the equipment has arrived.
With memories of the long Iraq war still fresh, the political crosscurrents have been intense both domestically and overseas.
Dozens of lawmakers, most of them Republican, have signed a letter saying Obama should not take military action without congressional approval, and top leaders of both political parties are urging the president to consult more closely with Congress before giving an order to launch hostilities.
Despite the urgings, there has been little or no discussion about calling Congress back into session to debate the issue. Lawmakers have been on a summer break for nearly a month, and are not due to return to the Capitol until Sept. 9. Obama has not sought a vote of congressional approval for any military action. Neither Republican nor Democratic congressional leaders have challenged his authority to act or sought to have lawmakers called into session before he does.
Senior White House, State Department, Pentagon and intelligence officials met for an hour and half Friday with more than a dozen senators who serve on the Foreign Relations and Armed Services committees, said Sen. Chris Coons, D-Del. He described the discussion as "open and constructive."
The White House will brief Republican senators in a conference call Saturday at the request of Senate GOP leader Mitch McConnell, R-Ky., a spokesman for the senator, Don Stewart, said.
Obama's efforts to put together an international coalition to support military action have been more down than up.
Hollande has endorsed punitive strikes, and told the newspaper Le Monde that the "chemical massacre of Damascus cannot and must not remain unpunished."
But British Prime Minister David Cameron's attempt to win a vote of approval in Parliament for military action ended in ignominious defeat on Thursday. American attempts to secure backing at the United Nations have been blocked by Russia, long an ally of Syria.
U.N. Secretary-General Ban Ki-moon has urged a delay in any military action until the inspectors can present their findings to U.N. member states and the Security Council.
