Iran missiles. 
Sigh...........
Israel's Iron Dome (America), designed (mostly), produced by Raytheon/General Dynamics, interceptor missiles cost between 1 Million - 3.5 Million a piece. 
Iran's latest missile attack, ~$100,000 a piece. 
Statistically,  KNOWING exactly where a missile is going to be BEFORE HAND, as in TESTING, Not live combat, we only have 70% chance of successful interception.  This is the best math that current technology can achieve. 
If you don't know where the missile is going to be, the %% is basically ffff'all. 
Isreel's genocide is not going to end well. Unless we send our troops to finish it for them.
