The gist of it is that the USA, KSA, and Israel all want Iran’s current government to be toppled as they are a direct military/economic/political threat.

What’s the logic here? Not just the conspiracy. But why now? Why at all? Is Israel gaining something that I’m not seeing? Destabilization the main goal? What’s the USA gaining here?

Israel is an ethnostate so they do ethnostate things, which means constantly attacking anyone they view as “not us”. Iran happens to be on the top of that list after Israel’s former enemies, Egypt, Syria, Jordan, Iraq, Lebanon, and KSA were passified via the US or Britain.

The US and KSA also want to secure their oil regime, and now that Venezuela is dealt with, Iran is next.

Why does the USA love Israel so much?

They have a significant economic and military investment in Israel, and many of those Israeli billionaires are a part of AIPAC, which successfully lobbies the US to do what they want.

A bonus is Christian zionism which reinforces the idea that Israel must exist to cause the second coming of christ, or the messiah for the Jewish zionists.
