“The Iron Dome is an economically unsustainable defense against rockets as cheap as the Palis are using.”
Interesting observation.
However….
The Israelis really don’t have much of a choice but to keep using their “economically unsustainable” defense system since they have nothing else (outside of extended and possibly unsustainable combat) with which to diminish the missile attacks.
In that sense, their defense policy is not unlike the United State’s _economic_ policy, which is to keep borrowing to prop up an unsustainable system, because there really aren’t any acceptable policies that stand a chance of being implemented.
Lasers are the answer to that conundrum, and you can be sure they are working on it.
