The cost of defence of Iran's attack probably amounted over Rs 8,000 crore to Israel and its allies wheres Iran used weapons of around Rs 800 crore to attack Israel, according to a media report quoting analysts.
Whether Israel is willing to risk a direct strike would partly depend on how confident it is that it can thwart further attacks by Iran, which described the weekend salvoes as reprisals for a lethal Israeli strike on its generals in Syria.
Further escalation could see Iran opting for more powerful weapons from an arsenal which analysts say includes more than 3,500 missiles and drones numbering in the low thousands.
Israel’s multi-layer air defence is built around the high-altitude Arrow systems successfully used over the weekend, the mid-range David's Sling and the short-range Iron Dome which has fended off thousands of rockets fired from Gaza and Lebanon.
On Wednesday, US President Joe Biden urged Congress to pass an aid package that would replenish Israel’s air defences.
Brigadier-General Doron Gavish, head of Israel’s air defence task force, said Israel has been working overtime to rebuild its stockpiles in preparation for another possible attack from Iran or its proxies.
Were the Israelis to face Iran alone in a future flare-up, they could use Iron Dome and David’s Sling as more thrifty fallbacks: Any missiles that might be missed by Arrow could be tackled by the lower-altitude systems.
