From page 64 of my favorite Little Red Book:
Most of all, I shall refrain from making any prediction upon the future. It is a month ago that I remarked upon the long silence of Herr Hitler, a remark which apparently provoked him to make a speech in which he told the German people that Moscow would fall in a few days.
That shows, as everyone I am sure will agree, how much wiser he would have been to go on keeping his mouth shut.
