“I believed then, as most conceited young people do, that a strong rational argument will carry the day if sufficiently well supported by substantiated facts. This, of course, is nonsense. Once a group of powerful people have made up their minds on something, it develops a life and momentum of its own that is almost impervious to reason or argument. This is particularly true when personal ambition and bravado are involved. In this case even an appeal to fear of ridicule and historical condemnation would not have worked. The decision had been taken at the highest level, and a vast military machine had been set in motion. The opinions of a young intelligence officer were not going to stop it.” – Brian Urquhart, “The Last Disaster of the War” [regarding the fiasco of Operation Market-Garden in the Second World War]
