I didn't say Gaza was occupied by Israel niggly it is blockaded by the Israelis with all ports closed and all supplies passing through check points. There are opinions that the blockade is effectively reducing living conditions to the equivalent of the Middle Ages. There have been many appeals to ask for medical supplies to be allowed in and some restrictions have been relaxed, but the situation remains dire. The occupied territories are land over run by Israel and since colonised by them.
From Wiki
The International Court of Justice,[1] the UN General Assembly[2] and the United Nations Security Council regards Israel as the "Occupying Power".[3] UN Special Rapporteur Richard Falk called Israel's occupation "an affront to international law."[4] The Israeli High Court of Justice has ruled that Israel holds the West Bank under "belligerent occupation".[5] According to Talia Sasson, the High Court of Justice in Israel, with a variety of different justices sitting, has repeatedly stated for more than four decades that international law applies to Israel's presence in the West Bank.[6] Israeli governments have preferred the term "disputed territories" in the case of the West Bank.[7][8] Officially Israel maintains that the West Bank is disputed territory.[9]
Palestine isn't a huge state and its people are denied basic human rights NOTHING can justify such treatment.
