But he demands to know, how can we defeat Germany if we do go to war? He knows the answer to that better than anyone. We can defeat Germany only by obtaining mastery of the air over Germany, then destroying the German air force; once the Luftwaffe is destroyed, the impact of that blow alone may cause the first crack in the military and civilian morale of Germany and lift the morale of the conquered peoples to aid in expelling their conquerors. Let me reiterate that the conquered peoples will never revolt until they see the possibility of successful revolt and that will come only with the first serious military setback of the Germans. Would we have to send an expeditionary land army? We probably shall have to send our best units, and do it quickly, to prevent German seizure of the West African ports and islands affording springboards to America. Our troops would be useful now in North Africa and the Near East. Wherever contact with the enemy can be had, we should be represented as strongly as possible. It is also likely that we shall need to send an A.E.F. to the continent, although not necessarily as large as in the last war. If we can get air superiority, it will mean the war is practically won. I should expect Germany then to crack up. Even if she did not break down at once, the demoralization entailed by loss of control of the air would be so great that landings on the continent should be feasible at almost any place the Allies chose. Lindbergh persistently asks where we could land an expeditionary force. The answer is that if we get there in time we shall have an excellent base of operations across the seas, Great Britain. From there the coast of Nazi Europe presents hundreds of opportunities for invasion, once the Nazi air force is eliminated. Lindbergh demands to know how long it would take to win if we think, contrary to his judgment, that we can win. I should think it would take a minimum of three years after we enter the war, maybe four, possibly five or six. It can be accomplished only by expanding our present aircraft production program, which has orders now for 80,000 planes, to whatever dimensions prove necessary. This depends on how many planes the Germans are able to produce from their own and conquered factories, including all the facilities of their conquests in the East. We shall certainly have to think in terms of hundreds of thousands of planes. We and the British will have to supply the pilots and crews and ground crews for these planes, and it may be that our Air Corps will number upwards of a million before we are through. We have the men and the machines to do it.
