Could you explain what you mean when you mention that "First the West reneged on the Nuclear deal with Iran"? I understand why the current situation would encourage Iran to pursue nuclear weaponry, but the agreement as far as I know did not include any defensive pact, so Iran didn't agree to forsake development of nuclear weaponry under the promise of protection from the west (which is now proving to be ineffective), it promised to forsake nuclear weaponry in order to be allowed to pursue peaceful nuclear technology. So what related lesson is to be learned from the West reneging on the deal? Or are you saying that since the deal would have made Iran into a [nuclear threshold state](https://en.wikipedia.org/wiki/Nuclear_latency https://en.wikipedia.org/wiki/Nuclear_latency), this is the West reneging on the deal to allow Iran the technology to defend itself, and the lesson is that they should never have relied on the West for that in the first place?
