Syria's War a Growing Threat to US Security

The civil war in Syria is posing a growing threat to U.S. national security, and it's forcing the Obama administration to re-evaluate its strategy.

Al Qaeda-linked operatives are working their way into the rebel forces and pushing out moderates. Officials say that could lead to potential terrorists bases to plot and carry out attacks against the United States.

President Barack Obama has avoided U.S. involvement in Syria so far.

But now the White House is re-examining alternative options, including drone strikes on rebel factions that may later try to attack the United States.
 
"We have to examine what the alternatives some might be proposing are and whether they're in our national security interest," White House press secretary Jay Carney told reporters Tuesday.

Last week, Obama said a military option was still not likely. He acknowledged "enormous frustration" with peace talks in Geneva, which ended without progress.
