1. Is there a meaningful deterrent against an anonymous atomic attack on the United States? If not--if there isn't a meaningful deterrent against a nuclear attack by terrorists or by enemy states using terrorists to strike the U.S. in a deniable way--how do you plan to prevent an atrocity like this from ever happening?
2. Is there any defense against a seemingly civilian, cargo ship-launched nuclear attack on the United States--including both a direct strike on a U.S. coastal city and an EMP attack? If there isn't a defense against a ship-based attack on the U.S. homeland, why isn't there one, and what do you intend to do about it?
