The book’s most controversial thesis is not that MNT is plausible and should be taken seriously; it is that the only coherent response to this technology’s military implications is to develop global governance structures that supersede existing national powers. “The traditional way of guaranteeing national security–namely the threat of armed force–may no longer be compatible with the advance of technology,” he argues. And since security “can no longer be reliably ensured by national armed forces,” he prescribes “strengthened international institutions and international law, in particular criminal law with prosecution of perpetrators, moving into a direction toward an international monopoly of legitimate force, strong enough to prevent or punish threats or use of illegal force.”

a book that talks about MNT dangers as of ca. 2003 does not assuage your concerns, exactly. things are moving much faster than that..
