"[The Syrian people's] peaceful protests were met with slaughter ... The international community recognized the stakes but the response hasn't met the scale of the challenge," he said.

Aid can't keep pace with the suffering, the president said, confirming that the U.S. will send an additional $340 million in aid to the region. "No [amount of] aid can take the place of political resolution to give people the chance to rebuild their country," he said, but it can help people survive.

President Obama contended that to believe that any other regime carried out the chemical attack would be an "insult to human reason."

"I know in the immediate aftermath, there were those who questioned a limited strike," he said, but later added that there "must be consequences" if the Syrian regime can't keep its commitments to rid the nation of its chemical weapons as it has agreed.
