Good points in this article but it should not be forgotten that much of America's wartime science came at a vast discount because the Briitish threw open their vast research projects as part of their appeal for aid. The breaking of the sound barrier, for example, rested very very heavily on UK work in this area. Without that science given by the Brits (And being Irish I have little love for my former neighbours), the advances of the US would have come at a much higher price and delay.
Dr. Kealey has written extensively on this subject. I believe he approves of government funding of defense-related research.
