Conclusion
The fact that a number of aspects of maritime blockade law are not settled in customary law infers that any state that engages in blockade operations risks the possibility that its actions will be found to have been unlawful. Because the consequences of a blockade can be so deleterious to vulnerable civilian populations, it is necessary that a legal framework for maritime blockade be established. At the core of any such framework must be the requirement to address humanitarian issues and concerns. Without such initiatives, the law of blockade will remain mired in the early twentieth century, and states engaging in this method of warfare will do so under a cloud of legal ambiguity.
