US Senate Majority leader Chuck Schumer said at the March for Israel rally in Washington DC: "We are here united, Democrat and Republican, House and Senate, to say: 'We stand with Israel."
"There are no words for the horror that happened one month ago in Israel. The most Jews killed in a single day since the Holocaust. It brings back much darker days. And let us not forget history. History shows that when the world ignored antisemitism in the last century, it led to the worst catastrophe in human history, six million Jews murdered in the Holocaust," he said.
"Let us not forget history. History shows that Israel was almost destroyed — in 1967, in 1973. We cannot, we must not let that happen again.
"Let us not forget history. History shows that antisemitism has been deep in the core of Europe for centuries and that too many European nations have never been friends of Israel.
"Let us not forget history. History shows that when antisemitism rears its ugly head, if it's not dealt with forcefully and directly, it grows into a deadly force."
