What I said so far is not just an opinion:

>> The United Nations, International Committee of the Red Cross, and many human rights organization however continue to consider the occupying power as Israel controls Gaza's borders, with the exception of the Egyptian border, airspace and access to the sea and exercises what they consider to be effective military control over the territory.[21][22][23]

>> In his statement on the 2008–2009 Israel–Gaza conflict, Richard Falk, United Nations Special Rapporteur wrote that international humanitarian law applied to Israel "in regard to the obligations of an Occupying Power and in the requirements of the laws of war."[181] Amnesty International, the World Health Organization, Oxfam, the International Committee of the Red Cross, the United Nations, the United Nations General Assembly, the UN Fact Finding Mission to Gaza, international human rights organizations, US government websites, the UK Foreign and Commonwealth Office, and a significant number of legal commentators (Geoffrey Aronson, Meron Benvenisti, Claude Bruderlein, Sari Bashi, Kenneth Mann, Shane Darcy, John Reynolds, Yoram Dinstein, John Dugard, Marc S. Kaliser, Mustafa Mari, and Iain Scobbie) maintain that Israel's extensive direct external control over Gaza, and indirect control over the lives of its internal population mean that Gaza remained occupied.[182][183] In spite of Israel's withdrawal from Gaza in 2005, the Hamas government in Gaza considers Gaza as occupied territory.[184]

>> Several rights groups have characterized the situation in Gaza as an "open-air prison", including the United Nations,[193] Human Rights Watch,[194] and the Norwegian Refugee Council.[195] This characterization was often cited by a number of human rights activists, politicians, and media news outlets reporting on the Gaza-Israel conflict and the wider Palestinian-Israeli conflict.[196][197][198][199][200][201] Former British Prime Minister David Cameron,[202] US Senator Bernie Sanders,[203] former Israeli diplomat Gideon Levy,[204] and Israeli historian Ilan Pappe have endorsed this characterization as well.[205]

>> Human Rights Watch issued a report on the situation in the Gaza Strip, which it called an "open-air prison" due to the blockade and held Israel responsible as the occupying power, and to a lesser degree Egypt, which has restricted movement of Palestinians through its border.[194]

Seems we have a choice now, either we believe all the entities having prepared extensive reports (all cited in the wikipedia article) or we believe Israelian PR and legalese on the status of Gaza according to international law (which doesn't change the an iota when it comes to the humanitarian situation there). Your choice.

I am not saying Hamas actions are justified. And I am not saying Israel shouldn't get support. Ehat I am saying is, that we cannot ignore the humanitarian crisis affecting millions of people that is at the core of the conflict. And whatever support the West can give should aim at renewed, and serious, peace talks. That means that Israel has to give up something, too. After all, Israel has the right to exist as a state the same way Palestinians have the right to live freely, un-oppressed and peacefully.
