So wait ... you're going to use terror attacks and extrajudicial killings in foreign countries as an argument to defend Iran? Iran is responsible for the civil war in Lebanon, and thus for at least hundred thousand dead in extrajudicial killings. So your argument, even if we accept everything as 100% true ... Iran is at least 1000x more guilty than Israel. Or just take [1] ...

So it seems strange to use this as an argument to defend Iran. Bad faith, even.

As for diplomacy: Iran signs treaties ... then just refuses to uphold them. For example, Iran signed, then pretty openly violated it's nuclear non-proliferation treaty obligations [2], same with the famous nuclear deal.

But, even where it comes to pretty basic things: Iran signed the human rights treaties, including the Geneva convention, and hangs gays and minors as a matter of course (according to amnesty #1 worldwide with hundreds of minors executed, and actually increasing the rate over time), attacks religious minorities, women, the government has a side business in kidnapping foreignors ...

Or other treaties. Iran signed freedom of navigation treaties, and has for decades violated them. Hell, Iran violates the international telecommunications union treaty.

The problem: Iran cannot be negotiated with, for the simple reason that they do not respect deals they make. There's no point in negotiating since their behavior does not change when they make deals. They make promises, and ignore them. They sign treaties, and boast openly about violating them.

You failed to mention that Iran violated the deal only after Trump withdrew the US from it...

Its hard to negotiate with Iran when Israel keeps killing their negotiators.
