"The simpler of the two, Einstein, states: “My first axiom /in/ the quest of international security involves the unconditional surrender by every nation of its sovereignty /to/ a legislative and judicial body to settle every conflict arising between nations”. Yet, “strong psychological factors are at work, which paralyze these efforts. Small determined groups regard warfare and the manufacture and sale of arms as occasions to advance their personal interests”. Greed."
Surrendering the nations' sovereignty to a worldwide "judicial body" (?) just asks a different question: who will keep this judicial body honest? Who watches the watchers? Ironically "Greed" in the form of international trade, and mutually assured destruction (Thanatos itself) has kept the world safe from self immolation.
