Well, Israel has been stockpiling US missiles for years as well as more recently obviously infiltrating Iran with drones for this very event. There's just no way with modern military tech that any defense system can't be overwhelmed simply with numbers. Tonight's attack by Iran on Israel with its again, endlessly US funded & supplied missile defense systems alongside Israels own "Iron dome" has been unable to stop Iranian missiles raining down on Tel Aviv, somewhat proving the point.

Iran did though seem to have neglected to take it's important Scientists and military personnel into defensive protection ...but these threats have been going on for thirty years... who wants to live down a hole "just in case"?
