The idea of the "humanitarian city" proposed by Israel Katz is highly controversial and may never be implemented.
Some commentators have suggested the real aim of floating the plan was to increase pressure on Hamas during ongoing ceasefire talks, while also appeasing right-wingers in the cabinet who oppose any truce.
The military had been asked to put together a detailed proposition, but Netanyahu dismissed it as far too costly and complicated, two Israeli officials who were present said, and ordered them to come up with something cheaper and faster.
An Israeli military source said it was a complex initiative that required intricate logistics for infrastructure such as sewage, sanitation, medical services, water and food supplies.
While I don't agree with the idea of a "humanitarian city" (and many within Israel don't agree with the idea either) no one apart from you has suggested it is proposed to "make it easier for them to bomb the Palestinians". The idea being proposed is that the new city or camp is built during the 60 day ceasefire and is done to separate citizens from Hamas via screening as they enter.
Your comment is hyperbole and reveals your bias that Israel are pure evil.
