My credibility is not on the line. The international community's credibility is on the line and America and Congress's credibility is on the line because we give lip service to the notion that these international norms are important.
When those videos first broke and you saw images of over 400 children subjected to gas, everybody expressed outrage, how can this happen in this modern world.
Well, it happened because a Government chose to deploy these deadly weapons on civilian populations.
– President Obama
So, the question is, how credible is the international community when it says this is an international norm that has to be observed.
The question is how credible is Congress when it passes a treaty saying we have to forbid the use of chemical weapons.
I do think that we have to act because if we don't we are effectively saying that even though we may condemn it and issue resolutions and so forth, somebody who is not shamed by resolutions can continue to act with impunity and those international norms begin to erode.
