I love how any discussion where Israel is mentioned turns into a pro Israel/ anti Israel argument. Let us please avoid the argument where it is not prurient, I.E. it is OK to discuss whether Israel would attack Iran it is not OK to argue over whether Israel oppresses the Palestinians as it is not relevant to the discussion.
Yes - but who has said anything about that?
The argument is about whether there is an existential threat to Israel. In reality, the only time there ever was one was at the time of the British withdrawal, when the Arab states had the military strength, if used well, to defeat the Haganah, Irgun & Lehi & destroy the nascent state of Israel. But the Arab forces consisted of half a dozen organised forces (national armies & the ALA) plus multiple local militias & irregulars, with differing war aims, & no unified command or even the most basic co-ordination of forces. Some groups of Arab villages, for example, were more or less neutral, refusing to send their militia off their own land - which didn't always save them from being evicted by the Israelis. The Israelis had already made a secret agreement with Jordan, which had the second largest & by far the most efficient Arab army. Egypt, which had the largest & most heavily armed force had limited objectives (regardless of rhetoric), mostly to do with grabbing some of the proposed Palestinean state & the Negev for itself.
There has never been another attempt by any Arab force, state or coalition to destroy Israel.
In 1956 Israel attacked Egypt, in co-operation with France & the UK.
In 1967, Israel felt threatened, so launched what it thought of as a pre-emptive attack, which was blindingly successful because the Arab armies & air forces attacked were not, despite the fiery rhetoric & hostile gestures which had preceded the Israeli attack, prepared for war.
Nothing happened in 1968.
In 1969-70, one Arab state tried to exert military pressure in order to get back lost territory by negotiation, & failed.
In 1973, two Arab states attacked Israel with the limited objective of regaining lost territory. They lost the war, but one of them subsequently got by negotiation what it had fought for - and that border has been pretty peaceful ever since.
So, what does this add up to? There are undoubtedly many Arabs who would like to see the end of Israel, but they don't pose an existential threat to it. Most Arab states have devoted more effort to fighting other Arabs, or (in the case of Iraq) Iran, than Israel. They don't feel an existential threat from Israel, & without that, they're not going to unite against it. No Arab state has attacked Israel for almost 40 years. Israeli military superiority over its immediate neighbours is overwhelming.
