States not only have a right, but a duty to prevent arms from reaching terrorist groups like Hamas and the other Palestinian terror groups operating in Gaza, and the blockade fufills that responsibiity. Under Security Council Resolution 1373, which was adopted under Chapter VII and is therefore binding, Israel, Egypt and all other states are required to take steps to criminalize and prevent all material support – active or passive, direct or indirect – to terrorist groups. Thus, all states bordering Gaza are legally obliged to prevent the flow of arms and other materiel to Hamas. Israel is also a party to the International Convention for the Suppression of Terrorist Bombings, which renders it criminal for any individual, Israeli or not, to supply rockets, mortars and missiles to Hamas and the other Palestinian terrorist groups. Israel and other state signatories are required to take steps to punish such criminals.
In addition, all states have the right to control their own borders. Israel has the right to prevent the flow of arms to Gaza across its own border with Gaza. Egypt has the same right to prevent the flow of arms across its Gaza. And Israel has the right to demand that Egypt exercise this right both on the grounds of Israeli-Egyptian agreements requiring Egypt to do so and on the basis of Egypt’s obligations under 1373.
