Charles Lindbergh Testifies Before the House Foreign Affairs Committee

Colonel Lindbergh, an aviation expert, expresses skepticism about Britain's ability to defeat Germany, even with U.S. aid, and suggests a negotiated peace. He argues that an air invasion alone is not feasible, as it would have been attempted by Germany against England if possible. Lindbergh believes that successful invasions require a combination of air, land, and sea forces, and are unlikely without an internal collapse in the target nation.
