Over the weekend, President Obama spoke at a special Holocaust Memorial ceremony in the Capitol Rotunda, where he pledged never to be silent in the face of Anti-Semitism.

"How do we ensure that "never again" isn't an empty slogan, or merely an aspiration, but also a call to action?

I believe we start by doing what we are doing today -- by bearing witness, by fighting the silence that is evil's greatest co-conspirator."

He was praised by Elie Weisel for his decision to boycott the Durban II conference in Geneva as well.

This praise was important because he has been attacked by some right-leaning groups for his tactics of engaging Israel's enemies to try to get them to change their policies rather than following Bush's approach of ignoring them while they built alliances.
