The genocide of Palestinians in Gaza is the longest and most expensive military campaign in Israel's history, costing an estimated $142 billion so far and set to approach roughly $169 billion, Haaretz reported on 16 August.

Tel Aviv's genocide has driven Israel's national debt up by some $130 billion, with the state set to spend around $500 billion on the military over the coming decade, according to Haaretz. 

Webmaster Addition: I wonder where Israel plans to get that money! :)
