I proposed converting our stockpile of fissile materials to non-
threatening impulse units at an AIAA conference in Dayton Ohio in
1990, as a way to avoid the threat of loose nukes following the
collapse of USSR. I showed how this was a better approach to non-
proliferation since it inspired cooperation and cost less than SDI and
had longer lasting benefits.
Since that time I have repeated my points any time that seemed
beneficial.
I wish I could take absolute credit for all these ideas. However,
they were explored rather fully by Leo Szilard as early as 1934. He
even wrote an addendum to Einstein's paper to FDR in 1940 noting the
importance of the long-range nuclear rocket. It was this addendum
that caused Truman to include rocket scientists in Project Paperclip
in 1945 by JIOA division of OSS.
So, its not like folks at the highest level don't know the stakes and
capabilities or haven't taken action on them.
I am hopeful.
