CRN has come under fire for saying that some kind of global administration will probably be needed to reduce the dangers of molecular manufacturing.
First, there's a huge difference between global administration and world govermnent. The International Atomic Energy Agency is a global administration.
Second, consider this interesting quote, from the 1960's Eighteen-Nation Conference on Disarmament, as stated in "Psychological factors in Soviet disarmament negotiation", Conflict Resolution IX:1. The Soviet representative, Mr. Zorin, cited the New York World Telegram in accusing the U.S. of demanding of all countries "...the establishment of international institutions which would encourage countries to give up the greater part of their national sovereignty: the undoubted and unconditional recognition of the jurisdiction of the International Court of Justice; the acceptance of supranational inspection and verification; willingness to make national security dependent on an international peace force under a greatly changed and strengthened United Nations." International courts, cross-border inspections, and strong UN... funny how those are exactly the things the US is currently opposed to. That implies the opposition may be more for convenience or short-term advantage than a matter of principle.
Finally, a quote from the Russell-Einstein Manifesto, written in response to the development of H-bombs: "Here, then, is the problem which we present to you, stark and dreadful and inescapable: Shall we put an end to the human race; or shall mankind renounce war? People will not face this alternative because it is so difficult to abolish war. The abolition of war will demand distasteful limitations of national sovereignty."
So if you want to argue that extremely powerful weapons are compatible with "business as usual," feel free to argue against Einstein. By the way, Joseph Rotblat, the last surviving signatory of that manifesto, says "It has great relevance today" and worries that atom bombs are becoming "a weapon of first resort" once again.
