The New York Times describes President Obama's visit to Yad Vashem, which you can observe in the pictures below:
After rekindling the eternal flame and laying a wreath at the Yad Vashem Holocaust memorial, a solemn President Obama spoke on Friday of a collective “obligation not just to bear witness but to act” against racism “and especially anti-Semitism” as he wrapped up his three-day visit here with a trio of symbolic pilgrimages.
“We have the choice to ignore what happens to others or to act on behalf of others,” Mr. Obama said after a tour of the museum and a brief memorial service.
“Our sons and daughters are not born to hate, they are taught to hate,” he added. “The state of Israel does not exist because of the Holocaust but in the survival of a strong Jewish state of Israel the Holocaust will never happen again.”
