Being able to send weapons and dollars to "moderate" anti-Assad groups may impossible:
The assault this month was led by the Nusra Front, Al Qaeda’s arm in Syria, which claimed the spoils. By contrast, many of the first Syrians to rise up against Mr. Assad in 2011 — civilian demonstrators and army defectors alike — followed the battle from the sidelines here, unable to enter Syria under threat of death from the extremists of Nusra and its rival group, the Islamic State.
As Syria’s war heads toward its fourth year, the complex battleground is increasingly divided between the government and the extremists, leaving many Syrians feeling that the revolution on which they gambled their lives and livelihoods has failed.
