these werent shittly little rockets they were ballistic missiles costing ~$20million each and iron dome interceptors cant target them so arrow2s and other more expensive interceptors were needed. an attack like this the entire country went into their bunkers and so more things might be let through, buildings and important infrastructure was defended but the cost of these interceptors are themselves a couple million each. a lot more than a bag of concrete. some of these missiles were intercepted in space.
