and Hamas or anyone else will fail in “destroying Israel”.

Israel is not “an idea.” It’s a genocidal white supremacist settler-colonialist state. And yes… those can be destroyed. You are correct, though… once destroyed, the white supremacist “idea” of Israel will live on. Just like the white supremacist ideas of the Antebellum South, Nazi Germany, Rhodesia and Apartheid South Africa lives on. But apart from voting for the likes of Trump or joining the KKK they won’t have any power in the real world.
