> Of those, perhaps Israel and maybe Qatar can be considered defensive actions.

The regime started a proxy war against Israel decades ago, financing Hisbollah and eventually also Hamas, both with the official goal of destroying Israel.

Before the regime came into power, Iran had good relations to Israel.

So no, there's nothing 'defensive' when it comes to Iran's actions.

Actually, after the regime came into power they also had good relations with Israel. As long as they thought they could win the Iran-Iraq war they kept good relations (Iran-Iraq war: 2 years of Iraq attacking Iran, 7 years of Iran attempting to conquer Iraq). In fact Israel saved many high ranking Iranian officials from Iraqi assassination.

Just shows: dictators will show no loyalty or gratitude. The second they can use you as a cheap excuse to stay in power and abuse that power, you better believe it will happen that very second.

Iran has shown they will abuse everyone every way they can. This is the regime that is SO pure in their religious beliefs they distributed "plastic keys to heaven" to their cheapest demining equipment (primary school children, to the point that one problem was sometimes the kids weren't yet heavy enough that they wouldn't trigger an anti-personnel mine that an adult soldier coming later would still not be safe)
