Exit and entry into Gaza is prohibited by sea and air. There are only three crossings to go in and out of Gaza, two of them controlled by Israel and one by Egypt. According to a 2022 report by the United Nations Office for the Coordination of Humanitarian Affairs, the blockade has significantly reduced movement of people and goods due to reduction in number of exit permits by Israel.[2]
Crossings were repeatedly shut and buffer zones were reinstated. Imports declined, exports were blocked, and fewer Gazans were given exit permits to Israel and the West Bank.
exactly the same scenario between uk and France. Where you can’t go to France without French permission. And you can’t enter uk via air or water because France doesn’t allow it. Maybe next time use a better example.
regarding water, maybe if Israel didn’t impose rules about how to collect water and use it as a weapon then gaza wouldnt need to be provided water

One of its most devastating consequences is the impact of Israel’s discriminatory policies on Palestinians’ access to adequate supplies of clean and safe water.
November 1967 the Israeli authorities issued Military Order 158, which stated that Palestinians could not construct any new water installation without first obtaining a permit from the Israeli army. Since then, the extraction of water from any new source or the development of any new water infrastructure would require permits from Israel, which are near impossible to obtain. Palestinians living under Israel’s military occupation continue to suffer the devastating consequences of this order until today. They are unable to drill new water wells, install pumps or deepen existing wells, in addition to being denied access to the Jordan River and fresh water springs. Israel even controls the collection of rain water throughout most of the West Bank, and rainwater harvesting cisterns owned by Palestinian communities are often destroyed by the Israeli army. As a result, some 180 Palestinian communities in rural areas in the occupied West Bank have no access to running water, according to OCHA. Even in towns and villages which are connected to the water network, the taps often run dry.
