Political, as this is a very political war!
Let's be clear about what is happening. When the Israeli colonists left the Gaza strip the population wanted to work at producing agricultural produce, as the colonists had been doing, and to build industries. The Dutch government provided money to build a port and an airport to support these activities. Shortly after building began it was destroyed by the Israeli military. Import and export should be by way of Israel. This meant that too often agricultural produce in transit was delayed long enough for it to spoil and that lost the exporters their market. Industrial development was severely limited by restrictions on the imports of machines and materials. The result of this is only computer files and rockets are easily exported from Gaza and that most people are without a job. Gaza is the largest prison in the world.
I won't call Israel a Jewish state as I'm not anti-Jewish..
