"Barack Obama and Joe Biden will institutionalize the Proliferation Security Initiative (PSI), a global initiative aimed at stopping shipments of weapons of mass destruction, their delivery systems, and related materials worldwide. They will expand the responsibilities of its members, not only in stopping illicit nuclear shipments, but also in eradicating nuclear black market networks. A stronger PSI will produce greater international intelligence and police cooperation, maintain tougher export controls and criminal penalties for violations in countries around the world, and apply the tools developed to combat terrorist financing to shut down proliferators' financial networks."
