While getting sinwar is good, as b’avod reshoim rino; in the big picture his death would make no difference bc to quote a fictional character who remarked about one of his tens of wives being murdered:
“I’ll get another”.
So long as Gaza is not completely destroyed and conquered and subjugated they will continue to be an existential threat to Israel.
Israel was never interested in wiping out and controlling Gaza so this war was lost before it even started.
But Bibi Bibi he’s our man if he can’t do it no one can…..
