That's a pretty good indicator that Arrow is depleted and they have no way of replenishing it in numbers with money alone. We don't even have that many THAAD interceptors and most are needed elsewhere. Morality aside, Israel seems desperate

We've got a single digit number of these batteries operational, the *total* number of interceptors delivered in the system's life is like 800, and it's such an important system in the Pacific that China is in large part building out new nukes to swamp batteries

After that last strike it’s obvious Arrow’s cooked as a system. These interceptors have huge refresh schedules.
