Marshall, Blake, and Mike wrap up the America First series by dissecting the America First principles of non-involvement in World War II, then discussing the effect on America of the shockingly rapid 1940 fall of France, American support to Britain through Lend-Lease, Charles Lindbergh’s ascent to the leadership of the America First movement, the postwar lack of a reckoning for America Firsters, and the staying power of “America First” views. We conclude by sharing some final thoughts on how “America First” has never been what it might seem to be.
