U.S. President Barack Obama said Wednesday that he has not come to a decision on making a military strike against Syria, but said the goal of a limited action would be to deter future use of chemical weapons. "If we are saying in a clear and decisive but very limited way, we send a shot across the bow saying, stop doing this, this can have a positive impact on our national security over the long term," Obama told Public Broadcasting Service (PBS) in a televised interview. The president said the United States has concluded that the Syrian government is responsible for the attack a week ago in the suburbs of Damascus that killed hundreds of people. Obama said that the United States has examined evidence and does not believe the opposition fighting the Syrian government possessed chemical weapons or the means to deliver them.
