Clinton Reaffirms Pressure on Assad to Draw Down

A shift in favor of Syria's opposition could be on the horizon in the country's civil war, according to a U.S. official, but President Bashar al-Assad is not likely to leave any time soon.

The armed opposition is making important tactical gains that could eventually trigger a strategic shift in the conflict, the official told ABC News Wednesday, adding that pressure on the regime is mounting and Assad's forces are having difficulty beating back insurgent gains.

"Assad's levers of influence are fraying and his reach is contracting, but the regime core is a tough nut that doesn't seem to be cracking just yet," the official said. "Although pressure is mounting, it's difficult to say when the breaking point will come, because there's little to suggest that Assad is a cut-and-run kind of guy."


"Factional infighting is clearly something the opposition has to guard against to be successful," the official said.

Tuesday, NATO decided to deploy patriot missiles to defend Turkey, a step Secretary of State Hillary Clinton praised, saying it sends "a clear message" to Syria.

"It's a great tribute to NATO that this decision to deploy patriots was taken, because it's very much in line with the solidarity of our members. This is for defensive purposes, that's made absolutely clear in the statement that was agreed upon. It is solely for the defense of Turkey," Sec. Clinton said at a news conference in Brussels Wednesday. "I don't believe that it necessarily brings any greater attention to the tragedy unfolding in Syria, but it does send a clear message to the Syrians that Turkey has the full support of it's NATO allies."


Clinton condemned the use of chemical weapons in Syria, calling it a "red line" for the United States for a second time.



"The use of chemical weapons is and would be totally unacceptable," Obama said Monday. "And if you make the tragic mistake of using these weapons, there will be consequences, and you will be held accountable."


"I'm looking forward to the Friends of the Syrian People meeting next week where we will explore with like-minded countries what more we can do to bring this conflict to an end," Clinton said, "but that would require the Assad regime making the decision to participate in a political transition, ending the violence against its own people. And we hope they do so because we believe their fall inevitable. It's just how question of how many people will die until that day occurs."
