PRESIDENT BARACK OBAMA: "America is not the world’s policeman. Terrible things happen across the globe, and it is beyond our means to right every wrong. But when, with modest effort and risk, we can stop children from being gassed to death, and thereby make our own children safer over the long run, I believe we should act. That’s what makes America different. That’s what makes us exceptional. With humility, but with resolve, let us never lose sight of that essential truth."
