So I've got some questions for the hasbaristas in this thread. Please show me the law(s) under which Israel claims the right to impose this blockade on Gaza. And please cite the specific language in the law(s) that pertain to this specific case.

And if the law(s) pertain to the rights of belligerents in a war situation, please show me the parts that specify the rights of both sides. That is to say, what right does a country have to enforce a blockade, and what rights do a country have to defend itself against a blockade.
