Irony and politics

Perhaps not the ideal place for this so should someone feel this too out of place, please let me know and I'll move/delete.

Politics demands compromises where none seem even tolerable. What a terrible job! The thought of balancing justice, law, ethics and economics while making progress and maintaining popularity would exasperate me. I'm not a great multitasker.

FDR's Four Freedoms Address in January of 1941 is well know. There was a lot of sentiment to keeping the US out of the war that was consuming other countries. The fourth freedom, the freedom from fear, was explained as "means a world-wide reduction of armaments to such a point and in such a thorough fashion that no nation will be in a position to commit an act of physical aggression against any neighbor -- anywhere in the world."

Within a year the Manhattan Project shifted into high gear and started the biggest buildup of weapons ever known.

What does it take to do that kind of job?
