The attack on the Madleen is in complete violation of international law. The Israeli state had neither the legal authority to detain the ship's passengers in international waters nor confiscate the vessel and its stores of humanitarian aid. The boarding demonstrates Israel's utter disregard for the International Court of Justice's binding orders requiring unimpeded humanitarian access to Gaza.
The operation by Israeli forces was necessary to maintain Israel's legal naval blockade, which is consistent with international law. The FFC's actions, in contrast, were a publicity stunt, which would have achieved little compared to the extensive humanitarian efforts conducted through proper channels. Rather than being motivated by genuine concern, the activists on board the Madleen were provocateurs chasing clicks and popularity.
