"It's a Three-front War"

The situation in Syria is getting worse and Obama, Kerry, Biden have yet to back down from their earlier threats to join the fracas:

An al Qaeda spinoff operating near Aleppo, Syria's largest city, last week began a new battle campaign it dubbed "Expunging Filth."

The target wasn't their avowed enemy, the Syrian government. Instead, it was their nominal ally, the U.S.-backed Free Syrian Army.

Across northern and eastern Syria, units of the jihadist group known as ISIS are seizing territory—on the battlefield and behind the front lines—from Western-backed rebels.

Some FSA fighters now consider the extremists to be as big a threat to their survival as the forces of President Bashar al-Assad.

"It's a three-front war," a U.S. official said of the FSA rebels' fight: They face the Assad regime, forces from its Lebanese ally Hezbollah, and now the multinational jihadist ranks of ISIS.

Brigade leaders of the FSA say that ISIS, an Iraqi al Qaeda outfit whose formal name is the Islamic State of Iraq and al-Sham, has dragged them into a battle they are ill-equipped to fight.

Some U.S. officials said they see it as a battle for the FSA's survival.

All the more reason the United States should rescind any promises to aid the rebels and certainly any promises to be engaged militarily.

But will that happen?

What do you folks think?
