Rabbi Lau w/Obama @ Yad Vashem

Wrapping up a three day visit to Israel, President Barack Obama paid a visit to the Yad Vashem Holocaust Memorial museum commemorating the six million Jews killed by the Nazis during World War II, 

Chief Rabbi Yisrael Meir Lau told the story of his liberation from Buchenwald on April 11, 1945, by American forces, recounting the disbelief in the barracks when a chaplain entered and shouted in Yiddish, “'Jews, you are free.'”“This is the opportunity to thank you, to thank the American people, who came finally,” Mr. Lau said. Saying that one of the liberators apologized to him decades later for coming too late, the rabbi said to President Obama, “Yesterday you promised us that we are not alone. Don’t be too late.”
