A/HRC/15/21 259. In the past, Israel has not honoured its obligations referred to in the preceding paragraph. It is hoped that on this occasion the Israeli authorities and those concerned will carry out prompt, independent and impartial judicial investigations of violations of international law, including international humanitarian law and human rights law, with a view to bringing the perpetrators to justice. V. Conclusions 260. The attack on the flotilla must be viewed in the context of the ongoing problems between the Government of Israel and the Palestinian Authority and people. In carrying out its task, the Mission was exposed to the depth of conviction on both sides of the correctness of their respective positions. Similar disasters are likely to reoccur unless there is a dramatic shift in the existing paradigm. It must be remembered that might and strength are enhanced when attended by a sense of justice and fair play. Peace and respect have to be earned, not bludgeoned out of any opponent. An unfair victory has never been known to bring lasting peace. 261. The Mission has come to the firm conclusion that a humanitarian crisis existed on the 31 May 2010 in Gaza. The preponderance of evidence from impeccable sources is too overwhelming to come to a contrary opinion. Any denial of this cannot be supported on any rational grounds. One of the consequences flowing from this is that for this reason alone the blockade is unlawful and cannot be sustained in law. This is so regardless of the grounds on which one seeks to justify the legality of the blockade. 262. Certain results flow from this conclusion. Principally, the action of the Israel Defense Force in intercepting the Mavi Marmara on the high seas in the circumstances and for the reasons given was clearly unlawful. Specifically, the action cannot be justified in the circumstances even under Article 51 of the Charter of the United Nations. 263. Israel seeks to justify the blockade on security grounds. The State of Israel is entitled to peace and security like any other. The firing of rockets and other munitions of war into Israeli territory from Gaza constitutes serious violations of international law and of international humanitarian law. But any action in response which constitutes collective punishment of the civilian population in Gaza is not lawful in any circumstances. 264. The conduct of the Israeli military and other personnel towards the flotilla passengers was not only disproportionate to the occasion but demonstrated levels of totally unnecessary and incredible violence. It betrayed an unacceptable level of brutality. Such conduct cannot be justified or condoned on security or any other grounds. It constituted a grave violation of human rights law and international humanitarian law. 265. The Mission considers that several violations and offences have been committed. It is not satisfied that, in the time available, it has been able to compile a comprehensive list of all offences. However, there is clear evidence to support prosecutions of the following crimes within the terms of article 147 of the Fourth Geneva Convention: • Wilful killing; • Torture or inhuman treatment; • Wilfully causing great suffering or serious injury to body or health. 53
