"The German right explained its defeat in the Great War by accusing social democrats and Jews of sabotage. It said Germany would have won but that it had been stabbed in the back by alien forces pretending to be Germans, behind its own lines. The Corbynites have created a "stab in the back myth" of their own. If it had not been for Zionists and liberals behind the Labour lines, Corbyn would now be PM."
