It cost Israel more than $1bn to activate its defence systems that intercepted Iran’s massive drone and missile attack overnight, according to a former financial adviser to Israel’s military.
“The defence tonight was on the order of 4-5bn shekels [$1-1.3bn] per night,” estimated Brigadier General Reem Aminoach in an interview with Ynet news.
“If we’re talking about ballistic missiles that need to be brought down with an Arrow system, cruise missiles that need to be brought down with other missiles, and UAVs [unmanned aerial vehicles], which we actually bring down mainly with fighter jets,” he said.
“Then add up the costs - $3.5m for an Arrow missile, $1m for a David’s Sling, such and such costs for jets. An order of magnitude of 4-5bn shekels.”
Economically, yes, but there’s plenty of other factors. Capacity to cooperate with the USSR was a resource, the capacity to see a Nazi-ruled Europe being way more of a long-term headache than facing them off was one, the US wanting to impress ole daddy stiff upper lip was, etc. Different actors come to different evaluations of those not so hard factors and that’s why they slug it out, to convince the other side that their evaluation is right. And sometimes they’re just plain delusional. And never underestimate the morale boost of an independence war (like Vietnam) or, even more so, an existential one (like Ukraine).
