Brutality of Syrian Rebels Posing Dilemma in West
In the more than two years this civil war has carried on, a large part of the Syrian opposition has formed a loose command structure that has found support from several Arab nations, and, to a more limited degree, the West. Other elements of the opposition have assumed an extremist cast, and openly allied with Al Qaeda.
Across much of Syria, where rebels with Western support live and fight, areas outside of government influence have evolved into a complex guerrilla and criminal landscape.
That has raised the prospect that American military action could inadvertently strengthen Islamic extremists and criminals.
