Comment on the Belmont Club : "Iron Sky"

The answer to Hezbollah's Iron Sky threat is Rafael's Iron Dome.
It certainly looks good.

The wiki says that the cost is prohibitive and laser systems are a better idea. Maybe but then again it is the wiki so what is their opinion worth? How many would be needed to ring Gaza? How many to guard the North? If Jordan turns belligerent, and they may under this king, then a reactive defense may not be viable. I still suspect that Israel needs to remove the threat from Gaza, either by getting the Egyptians to assume responsibility as they had before 1967 or by incrementally expelling the current population if they refuse to make peace.
