How about making peace with your neighbors. Then you won't need to deal with all of this expensive nonsense of dubious effectiveness. Return Palestinian land to the Palestinians. Let the Palestinians set up a state. The settlers should be allowed to stay where they are if they choose to and become Palestinian citizens; and offer Syria the return of their Golan Heights in exchange for peace and full normalization, like the US has with Canada and Mexico. End of problem. No iron dome is necessary.
