Aside from a potentially game-changing American intervention that shapes the fate of Iran’s nuclear program, two factors will help decide the length of the Israel-Iran war: Israel’s reserve of missile interceptors and Iran’s stock of long-range missiles.
Since Iran started retaliating against Israel’s fire last week, Israel’s world-leading air defense system has intercepted most incoming Iranian ballistic missiles, giving the Israeli Air Force more time to strike Iran without incurring major losses at home.
Now, as the war drags on, Israel is firing interceptors faster than it can produce them. That has raised questions within the Israeli security establishment about whether the country will run low on air defense missiles before Iran uses up its ballistic arsenal, according to eight current and former officials.
