It's quite incredible that ten months in and after one of the most brutal military campaigns since WWII, alongside the most documented genocide in human history which only resulted in the utter failure of defeating Hamas and completely isolating Israel on the international scene, you're still banging that drum.
Iran is a 3,000 years old major player of the region that will never go away. 46 years of sanctions, murders, and proxy-wars achieved the square root of feck all. Your view of the actors and dynamics in the region is a Disney one, watched through neo-con specs. What you advocated from day one after 10/7 will never never happen since Hamas is an idea. You defeat an idea with a better one, not with 2,000 pounds bombs or extra-judicial assassinations. Constantly poking at Iran will only lead to a major war in which there's no winner.
Hamas is a by-product of Israel's policies in the occupied territories, just like Hezbollah is a direct result of Israel's invasion of Lebanon in 1982. They aren't going anywhere no matter how many of their leaders you kill, unless you go for the root cause which is the Israeli Occupation of Palestine. Hamas will also be integrated one way or another into any serious peace talk, just like Arafat became a dialogue partner once Rabin understood that the hammer/nail policy lead to nowhere. A true shame that he was killed for seeing the light.
Terrorism is a very old, and highly subjective, political brand used to disqualify anyone the dominant side doesn't like. Hamas are terrorists, but so was Menachem Begin, a leader of Irgun before becoming Israel's PM. His organization was responsible for multiple acts of terrorism including attacks on civilians and the bombing of the King David Hotel. Or Yitzhak Shamir, terrorist, leader of the Lehi which carried out multiple massacres including Deir Yasin in 1948 and also future PM of Israel.
On a side note, it's absolutely amazing to see so many people firmly anchored in the democratic camp, including many posters here, cheering when Israel assassinates someone on foreign soil and continuously makes a mockery of every single international law. The cognitive dissonance, double standards and complete disintegration of any kind of moral compass taking place on this particular matter will be a case study for decades, if not centuries.
