Iron Dome works as intended, but would not be necessary if Israel wasn't annexing land that people already live on and consider home. That's what the Palestinians are mad about and what continues to radicalize them. If you stop doing the things Palestinians are mad about, there will be far fewer mad people and far fewer attacks, opening up a path to peace. Iron Dome is a symptom of the problem.
Iron Dome is used to continue and defend the encroachment onto Palestinian land. The retaliation against Palestinians (often those who have nothing to do with attacks) using primarily 5.56 rounds supplied by US/NATO (likely paid for by your taxes if you speak English!), rockets sent into private homes, or straight up billy clubs, is wildly imbalanced. But propaganda arms like .il websites and "just asking questions" guys in the comment sections of social media websites perpetuate the notion that there is somehow some balance that is reached only by deploying Iron Dome batteries. Media critics call this both-sides-ism and the news media outlets use it incessantly to muddy the waters on complex problems by drawing false dichotomies just as you have.
