Israel's "Iron Dome" defense system is said to repel the vast majority of rockets coming from Gaza. The Israeli authorities claim that the efficiency of the system exceeds 84%, meaning that out of every hundred rockets that the dome begins to track, it successfully intercepts at least 84 rockets.
Israeli propaganda evolved to say the dome's capabilities exceeded beyond 90%, with Iron Dome supporters portraying it as a great development of a project that began work on less than five years ago. A professor from the Massachusetts Higher Institute of Technology (MIT) in the United States, Theodore Postol, came out to say that the figures about the effectiveness of Iron Dome are incorrect.
