Terrorists as Pirates
The Legal Affairs magazine has a great [article comparing terrorists to pirates in the eyes of the law](http://www.legalaffairs.org/issues/July- August-2005/feature_burgess_julaug05.msp). One of the major obstacles has been finding a common definition that works under international law. As the author points out, in order to eradicate pirates, nations had to come together and recognize them as a special threat to all states.
“TO UNDERSTAND THE POTENTIAL OF DEFINING TERRORISM as a species of piracy, consider the words of the 16th-century jurist Alberico Gentili’s De jure belli: “Pirates are common enemies, and they are attacked with impunity by all, because they are without the pale of the law. They are scorners of the law of nations; hence they find no protection in that law.” Gentili, and many people who came after him, recognized piracy as a threat, not merely to the state but to the idea of statehood itself. All states were equally obligated to stamp out this menace, whether or not they had been a victim of piracy. This was codified explicitly in the 1856 Declaration of Paris, and it has been reiterated as a guiding principle of piracy law ever since. Ironically, it is the very effectiveness of this criminalization that has marginalized piracy and made it seem an arcane and almost romantic offense. Pirates no longer terrorize the seas because a concerted effort among the European states in the 19th century almost eradicated them. It is just such a concerted effort that all states must now undertake against terrorists, until the crime of terrorism becomes as remote and obsolete as piracy.”
