Who said they were?

"My favourite moment came when I pointed out that journalists should be on the side of those who suffer. If we were reporting the 18th-century slave trade, I said, we wouldn't give equal time to the slave ship captain in our dispatches. If we were reporting the liberation of a Nazi concentration camp, we wouldn't give equal time to the SS spokesman. At which point a journalist from the Jewish Telegraph in Prague responded that "the IDF are not Hitler". Of course not. But who said they were?" (thanks Hussein)
