> There was literally a puppet regime in the 70s backed and promoted by the US.

Yes. But do not think that the current regime in Iran is the one that overthrew the Shah. The current regime is the one that butchered and jailed the people who overthrew the Shah. It is of a less known fact, but it is the case.

> You also need to try to understand their point of view.

Sure. Every (even irrational) player has a point of view. Moreover, we can even try and understand it. However, it does not mean that we should not act.
