Of the three combatant nations – the US, Iran and Israel – the Israelis seem to be in the least hurry to end this war. They want to see as much as possible of Iran’s ballistic missile stocks destroyed, along with storage depots, command and control centres, radar sites and IRGC bases.
All of these, of course, can be rebuilt when the shooting stops so Israel wants Iran to understand there is a severe cost in doing so, namely that the Israeli Air Force is quite capable of returning and bombing them again in a few months’ time.
Israel sees Iran’s missiles and its suspect nuclear programme as an existential threat.
Iran has – or at least had, up until this war started – a highly-developed homegrown missile and drone industry. (It gave its ally Russia the Shahed drones that have pummelled Ukraine).
Iran has also been enriching uranium to 60% purity, far beyond the level needed for civil nuclear power.
Taken together, the government of Israeli Prime Minister Benjamin Netanyahu sees these twin threats as something Israel cannot live with.
