2 videos showing 3 failed intercepts. None have killed civilians nor military personnel. Figures by Israel indicate ~300 attacks were fired, the iron dome had a successful intercept rate of ~99%, which would be 3 failed intercepts then. So it's 3 failed, we can say 5 to be safe. I'm not gonna lie, man, it sounds like the iron dome works.
I'm not sure about failing but it can certainly be saturated. They don't have an infinite amount of interceptors. Which has been my question since Israel started striking everything around them, they are going to run out of ammo eventually for offensive and defensive operations. And what happens then?
