A democratically elected government that then flaunts the law and the constitution, such as illegally attacking another country without congressional approval, is a regime. Particularly when it has historically low approval ratings.

Israel's government is probably only in power as long as they continue to start and wage war against countries in the neighborhood. It was very convenient for them, that the attack of October 7th happened, just when ten thousands of people went on the streets to protest against their attempt to take away power from the judges and elevate themselves.

In the US the election might have been tempered with, according to newest reports, so the government might not even be actually democratically elected and Trump is playing the autocrat's playbook, going as far as arresting political opponents without a warrant.

Iran no question there.

That makes 3 out of 3 in my book.

I am not so sure your statement is footed on a solid base these days.

That will be hard to do with a whole Iraq in between. I don't think Israel's military has what it takes. They already struggled in Gaza and are on the lifeline of US support. US could probably not even do it with massive amount of effort, and it would turn into a second Vietnam for them. Without troops on the ground no chance anyway.
