The thing that kind of limits Iron Dome’s long term usefulness is that even when it works every rocket shot down still represents a loss for Israel in terms of a financial war of attrition. It looks cool, is technologically badass and prevents casualties but was also only every going to be a temporary stopgap measure. In some ways it’s actually counterproductive for the user since it conveys a (false) sense of near invulnerability on Israel and again raises the disproportionate capabilities of the two sides to the foreground.
