Just admit you make awful comparisons and fail to make analogies work.

Hitler, for one, had a specific fascist ideology comparable to Mussolini. I'd feel comfortable comparing the two. Not only based on their alliance and ideology alone, but also their actions taken.

When we compare people to Hitler, we generally make the assumption that we are talking about genocide, fascism, and an extreme passion for exterminating and villifying the "other" (whether that be Jews or Muslims or Slavs or something else). I wouldn't even make a comparison between Hitler and Netanyahu if I had to be professional and make time for an appropriate comparison.

On to Bin Laden, now. Why isn't he similar to Hitler? Back in the day, the US had a strategic alliance with Saudi Arabia. Backing the dollar with gold wasn't the best plan for us, we didn't gain a strong advantage doing so. Saudi Arabia was happy to help us with new US policy abroad. We went above and beyond to treat Saudi monarchs to the best life available, all at our expense. We even ignored the Saudis backing of people like Bin Laden back when we first knew of his type, all the way in the 1970s. We even used his allies and people with the Mujahideen that fought against the Soviets in the 1980s. Long story short, we had a blowback incident. 9/11 came around to hit us, likely with Saudis allowing it to happen while US intelligence was too incompetent or bogged down to act effectively (or maybe we knew and couldn't or wouldn't do anything). We went to war with Iraq and Afghanistan - not Saudi Arabia. Afghanistan was a failure the US contributed to actively for about 20 years, not including the interference from years prior. The Taliban is still governing Afghanistan today in fact. It wasn't anything like Hitler, except for the brutal anti-Communism. It certainly wasn't like Raisi either, considering that Iran and Afghanistan's Taliban aren't on the best terms.

I would compare Raisi to General Torrijos. Why is that? Because they were both nationalists, both concerned with sovereignty and not bending the will of their country to the US, yet each of them were not inherently accepting of either far-right extemist ideology or Communism (or other explictly left-wing political movements or ideologies). In spite of ideological differences, they both had a desire to stay neutral, choose key allies, and were rather accepting of liberation movements. People didn't really celebrate the death of Torrijos, at least in Panama. I wouldn't say people were exceptionally happy in Iran about the death of Raisi either. They weren't good leaders per se, but they stood on principles. I don't care for either figure myself, but I recognize who they were and what they fought for as humans.
