WASHINGTON — He said that if the United States does not stand up to Assad and against the use of chemical weapons, some world figures will believe "it's OK to use them with impunity."
Secretary of State John Kerry, testifying for the second consecutive day before Congress, insisted that the U.S. military response would be restricted as Americans fatigued by more than a decade of war in Iraq and Afghanistan show little inclination to get involved in Syria.
"I don't believe we're going to war, I just don't believe that," Kerry told the House Foreign Affairs Committee, citing the ground troops and long-term commitment that he said wars entail. "That's not what we're doing here. The president is asking for permission to take a limited military action, yes, but one that does not put Americans in the middle of the battle."
In the Senate, five Republicans, including potential presidential candidates Rand Paul and Marco Rubio, and two Democrats opposed the resolution, which is expected to reach the Senate floor next week. The timing of a vote is uncertain.
"I believe U.S. military action of the type contemplated here might prove to be counterproductive," Rubio said. "After a few days of missile strikes, it will allow Assad, for example, to emerge and claim that he took on the United States and survived."
Paul, a Kentucky conservative with strong tea party ties, has threatened a filibuster, although he acknowledged that proponents have the votes to prevail in the Senate, and he pinned his hopes on the House.
The notion of a contained operation has failed to sway many Republicans and Democrats in the House, who question why the U.S. should get involved now in a Syrian civil war that has killed an estimated 100,000, displaced millions and is in its third year. While House Speaker John Boehner, R-Ohio, and Majority Leader Eric Cantor, R-Va., have expressed support for military action, but rank-and-file Republicans remain reluctant or outright opposed.
