My older hearers will recall that after the First World War a number of our state legislatures and our school boards prohibited the teaching of German in the public schools. Today, I think, most of us would consider such a prohibition with regard to Russian, for instance, absurd and self-defeating. Even the man in the street could be made to see that it would be as if a regiment in the trenches, knowing that the enemy was preparing for an offensive, were ordered to close its eyes, so that it couldn't see what direction the attack was to take.
