What we also have to look at is the existential threat of Hamas, Hezbollah or even Iran against Israel.
Firstly Hamas and Hezbollah are groups of no more than a few thousand men at the most, relying mainly upon missiles and guns supplied on an ad hoc fashion by Iran, with Israel now making any supply of further arms virtually impossible. They rely upon guerilla warfare, they have no state of the art weaponry, no high tech drones etc., they have no armies with tanks and aircraft. Israel has one of the biggest armies in the ME with the most cutting edge weaponry supplied by the west. And they have nukes.
Iran has arms but little appetite for war despite the rhetoric, after years of crippling sanctions the country is on its knees and the regime know that a bloody war could cause the people to turn against them and so initiate regime change.
So Israel are fighting David rather than Goliath and the present narrative about an existential threat to Israel is complete hyperbole. As one commenter recently said ‘good job Israel has an iron dome.’ Perhaps we should just think about that for a moment whilst considering that nobody they are presently bombing to bits has this.
