So if did manage to would he not be big on nuclear weapons, and perhaps the cold war might be less cold, or just start later after FDR?I just don't see him running again in 1948, and if he did he would be defeated. People were willing to accept a third and fourth term because of World War II--the justification FDR himself used. Seeking a fifth term will simply be seen as a vindication of the anti-FDR charges that he aimed at dictatorship, a presidency for life, etc. (He would also be more vulnerable than Truman was to attacks on Yalta, "softness" toward Stalin, etc.)
