Did Groucho Marx Make A Comment on Israel?

He was supposed to have visited Israel in 1963, although he really didn't want to go, so, I'll have to employ my imagination:

Harpo was there (did Groucho follow his the brother?):-

Harpo's last letter to Truman— not dated, but sent in about May 1963— enclosed a photograph of himself standing in the Harry S. Truman Forest in Israel. "There were several reasons for taking this photo— mostly my great pride in there being such a place [as the Truman Forest] and such a man as you," Harpo wrote. "My reason for sending it is simpler— I thought you might not know how tall and strong the trees have grown. Hope its symbolical."
