Book excerpt: International Maritime Security Law by James Kraska and Raul Pedrozo defines an emerging interdisciplinary field of law and policy comprised of norms, legal regimes, and rules to address today's hybrid threats to the global order of the oceans. Worldwide shipping commerce, fishing fleets, pleasure craft, and coastal states are exposed to the menace of offshore terrorism, weapons of mass destruction, piracy, smuggling, robbery, marine insurgency and anti-access threats. Land-based institutions and maritime constabulary forces operate within an increasingly integrated network that blends elements of humanitarian law, human rights law, criminal law, and law of the sea, with inspection regimes, commercial enterprise, and marine safety and environmental stewardship. The new authorities fuse together a global maritime partnership among states, international organizations and commercial interests to protect the maritime commons from the most dangerous risks and hazards.
