WASHINGTON (CNN) - Senators John McCain and Lindsey Graham continued their all-out verbal assault on the Obama administration's handling of the Syria crisis, disparaging Saturday's U.S.-Russian agreement as "morally and strategically indefensible."
"It requires a willful suspension of disbelief to see this agreement as anything other than the start of a diplomatic blind alley," the senators said in a joint statement, "and the Obama administration is being led into it by Bashar Assad and Vladimir Putin."
Calling the agreement "meaningless," the Republican members of the Senate Armed Services Committee lambasted the White House's latest attempt to walk the country back from the brink of a military confrontation with the Syrian government.
Russia and the United States announced Saturday that they have reached a groundbreaking deal on a framework to eliminate Syria's chemical weapons.
Syria must submit within one week a comprehensive list of its chemical weapons stockpile, Secretary of State John Kerry said, and international inspectors must be on the ground no later than November.
McCain, of Arizona, and South Carolina’s Graham criticized the pact as the latest use of rhetorical gymnastics by the Oval Office, an evolution that has seen President Barack Obama go from labeling Syrian President Bashar al-Assad a "menace (that) must be confronted" to, in the words of McCain and Graham, "our negotiating partner."
"This agreement does nothing to resolve the real problem in Syria," the two said. "[Assad] can go on slaughtering innocent civilians and destabilizing the Middle East."
McCain and Graham have both advocated for a more muscular response to the Syrian government's alleged use of chemical weapons on August 21, recommending the administration provide more weapons to moderate opposition groups.
In the statement, the senators reiterated that "significantly" increasing the United States' support to vetted opposition forces inside Syria is the only thing capable of turning the tides of the raging civil war and creating "real conditions for a negotiated end to the conflict."
For the longtime senators, Saturday's agreement is more evidence that the Obama administration is unwilling to do what's necessary to stop the al-Assad regime, and now has fully retreated from its previous position of stating the Syrian despot "must go."
"Assad will use the months and months afforded to him to delay and deceive the world using every trick in Saddam Hussein's playbook," McCain and Graham said.
The senators blasted the proposed accord, which would not explicitly threaten the use of force if the al-Assad regime failed to place its chemical weapons stockpiles under international control, as "an act of provocative weakness."
Beyond the agreement's impact for Syria, the Republican duo say the developments underscore the United States' waning influence abroad and the president's poor stewardship of national security interests. McCain and Graham say Obama's reluctance to lead a more robust response will further embolden Syria's neighbor, Iran, to continue flaunting U.S. warnings about its nuclear program.
"We cannot imagine a worse signal to send to Iran as it continues its push for a nuclear weapons," the statement read.
While McCain and Graham sharply rejected the framework agreement, the chairman of the Senate Armed Services Committee weighed in favorably on the outcome of the talks between Kerry and Russian Foreign Minister Sergey Lavrov, praising the accommodation as "significant progress."
Sen. Carl Levin, D-Michigan, disagreeing with McCain and Graham's assessment, said the pact is "enforceable" and that he believes it will achieve "an even better outcome than the goals of the authorization approved just a few days ago."
Levin also backed the administration's handling of the negotiations. Unlike the Republican chorus headlined by McCain, Graham and Tennessee Sen. Bob Corker, Levin said the accord represents a strategic victory for the United States over their Russian and Syrian counterparts. Levin also insisted that the framework still leaves a military response on the table and that the Obama administration "remains prepared to act."
"Russia and Syria sought two things in any agreement: a promise on our part not to use military force, and an end to international support for the Syrian opposition," Levin said. "This agreement includes neither item."
