So why did he and the other liberals work on it? They opposed it and have said so. Just saw this post. Sorry. They worked on it because they thought Hitler was working on it and they couldn't allow him to get it first. Read Einstein's 1940 letter to Roosevelt...or Feynman's autobiography.
But they never liked it, they always had second thoughts, and their fears and doubts intensified when its use was proposed after Hitler was defeated.
The scientists attitude they knew best about sharing the atom bomb secrets for the greater good of mankind does not impress me.I believe their brilliant accomplishments in the scientific field do not translate when it comes to protecting my nations interest.I have read enough today to confirm my doubts about their ability to make national security a priority.They don't like security today at Los Alamos.Why should I be surprised about past perfidy.While most did not spy,they were useful idiots.
