And nearly eight in ten of those questioned in an NBC News survey released Friday morning say President Barack Obama should be required to get Congressional approval before launching any military attack against the forces of Syrian President Bashar al-Assad.

The poll, conducted Wednesday and Thursday, indicates 50% of the public says the U.S. should not take military action against Damascus in response to the Syrian government’s alleged use of chemical weapons against its own citizens, with 42% saying military action is appropriate.

But the survey suggests that if any military action is confined to air strikes using cruise missiles, support rises. Fifty percent of a smaller sample asked that question say they support such an attack, with 44% opposing a cruise missile attack meant to destroy military units and infrastructure that have been used to carry out chemical attacks.
