A big group of foreign policy experts, from across the ideological spectrum, is calling on President Obama to impose “meaningful consequences on the Assad regime” for their use of chemical weapons.

“At a minimum, the United States, along with willing allies and partners, should use standoff weapons and airpower to target the Syrian dictatorship’s military units that were involved in the recent large-scale use of chemical weapons.  It should also provide vetted moderate elements of Syria’s armed opposition with the military support required to identify and strike regime units armed with chemical weapons,” the experts write.
