Um, not supporting what Hamas is doing, but where should they set up those sites?
Gaza is a very crowded piece of real estate which makes it difficult to find a spot that isn’t close to a civilian target. Also, they want those sites to be hard to find and difficult to hit. That’s how wars are fought. You don’t make it easy for your opponents.
I reiterate; I do not support Hamas doing what they are doing. But I know enough about warfare to understand the strategy and tactics behind their actions.
