Questioned about the political impact of Strauss's work by Seymour Hersh, Cropsey said that common sense suggested that a certain amount of deception was necessary in politics:
- "That people in government have to be discreet in what they say publicly is so obvious - If I tell you the truth I can't but help the enemy.'" But there is nothing in Strauss's work he added, that "favors preemptive action. What it favors is prudence and sound judgement. If you could have got rid of Hitler in the 1930s, who's not going to be in favor of that? You don't need Strauss to reach that conclusion."
