"The other nations would get in the game. It would be silly and suicidal, of course, but it doesn't take brains to take a hand in this. All it takes is a very small group, hungry for power, a few airplanes and a supply of dust. It's a vicious circle that cannot possibly bestopped until the entire planet has dropped to a level of economy too low to support the techniques necessary to maintain it. My best guess is that such a point would be reached when approximately three-quarters of the world's population were dead of dust, disease, or hunger, and culture reduced to the peasant-and-village type.
"Where is your Constitution and your Bill of Rights if you let that happen?"
I've shortened it down, but that was the gist of it. I can't hope to record every word of an argument that went on for days.
The Secretary of the Navy took a crack at him next. "Aren't you getting a bit hysterical, Colonel? After all, the world has seen a lot of weapons which were going to make war an impossibility too horrible to contemplate. Poison gas, and tanks, and airplanes — even firearms, if I remember my history."
Manning smiled wryly. "You've made a point, Mr. Secretary. 'And when the wolf really came, the little boy shouted in vain.' I imagine the Chamber of Commerce in Pompeii presented the same reasonable argument to any early vulcanologist so timid as to fear Vesuvius. I'll try to justify my fears. The dust differs from every earlier weapon in its deadliness and ease of use, but most importantly in that we have developed no defense against it. For a number of fairly technical reasons, I don't think we ever will, at least not this century."
"Why not?"
"Because there is no way to counteract radioactivity short of putting a lead shield between yourself and it, an airtight lead shield. People might survive by living in sealed underground cities, but our characteristic American culture could not be maintained."
"Colonel Manning," suggested the Secretary of State, "I think you have overlooked the obvious alternative."
"Have I?"
"Yes — to keep the dust as our own secret, go our own way, and let the rest of the world look out for itself. That is the only program that fits our traditions." The Secretary of State was really a fine old gentleman, and not stupid, but he was slow to assimilate new ideas.
