In his Sept. 11 op-ed, "Full-court press on North Korea," Josh Rogin argued that maximizing sanctions against North Korea may be "the last chance to avoid a binary choice between a nuclear North Korea that can blackmail the world or war." But given the awfulness of that very possible choice, should not the United States also be offering North Korea very generous economic aid, as well as avoidance of sanctions, if it satisfactorily limits its nuclear arms program? And if North Korea refused to give up its intercontinental nuclear arms program even when offered such benefits — and adequate security guarantees — would not that make it clear that North Korea indeed intends to "blackmail the world" with nuclear weapons, and would that not in turn clarify the choices facing the United States?
