“I'm really convinced that our descendants a century or two from now will look back at us with the same pity that we have toward the people in the field of science two centuries ago.”

Essentials to Peace (1953)
Context: We have walked blindly, ignoring the lessons of the past, with, in our century, the tragic consequences of two world wars and the Korean struggle as a result.
In my country my military associates frequently tell me that we Americans have learned our lesson. I completely disagree with this contention and point to the rapid disintegration between 1945 and 1950 of our once vast power for maintaining the peace. As a direct consequence, in my opinion, there resulted the brutal invasion of South Korea, which for a time threatened the complete defeat of our hastily arranged forces in that field. I speak of this with deep feeling because in 1939 and again in the early fall of 1950 it suddenly became my duty, my responsibility, to rebuild our national military strength in the very face of the gravest emergencies.

Our situation has deteriorated so dramatically that we must choose between revolution or ecological collapse, mass extinction, and possibly our own demise. The twenty-first century is a time of reckoning.
