Chabad was viciously anti-Zionist until after the founding of the State of Israel. When Jews could have fled Europe and gone to Israel or America, Lubavitch rebbes opposed leaving Europe. The 6th Lubavitcher Rebbe, a vicious anti-Zionist in his own right, told followers there would be no war and that it was safe to stay in Europe. He did this from Warsaw in the summer of 1939, less than four months before WW2 began with the bombing and invasion of Poland. He was rescued by the American government. What did he ask for as he was brought to safety from amidst the destruction and horror? To save more Jews? No. The man asked for the rescue of his silver collection and his rare book collection – Sherlock Holmes in Yiddish translation along side of "sefarim". Not a peep from the holy man's mouth about saving Jews.
