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, and that "we will not repeat that moment."
Citing an imperative to act, the secretary of state 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."
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."
Obama long has been wary of U.S. military involvement in Syria's civil war, as he has been with tumultuous events elsewhere during the so-called Arab Spring. In the case of Syria, his 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-linked 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. Obama approved the shipment of small weapons and ammunition to the Syrian rebels after an earlier reported chemical weapons attack, although there is no sign the equipment has arrived.
