No, there is not the slightest scrap of evidence that Iran is trying to create such a thing, but then there's also not the slightest scrap of evidence that Iran is trying to create a nuclear bomb.
And yet, here are a bunch of celebrities in a video that certainly cost many more dollars than the number of people who've watched it, urging support for the Iran deal after hyping the bogus Iranian nuclear threat, pretending that the United States gets "forced into" wars, making a bunch of sick jokes about how nuclear death can be better than other war deaths, suggesting that spies are cool, cursing, and mocking the very idea that war is a serious matter.
And here's an otherwise intelligent guy in a video claiming that the Iran deal will prevent the "Iranian regime" (never a government, always a regime) from "gaining a nuclear weapon." Well, I say it also prevents Iran from gaining a Naked Muslim Ray Gun!
When you question supporters of diplomacy and peace with Iran on why they focus their rhetoric on preventing Iran from getting nukes, even though at least some of them privately admit there's no evidence Iran is trying to, they don't come out and say that they're cynically playing into popular beliefs, even false ones, because they have no choice. No, they tell you that their language doesn't actually state that Iran was trying to get nukes, only that if Iran ever did decide to try to get nukes, this deal would prevent it.
Well, the same applies to the Naked Muslim Ray Gun.
Be afraid. Be very afraid.
Or rather, stop being afraid. Don't listen to the pro-war propaganda even when it's parroted by the pro-peace advocates. It doesn't improve your thinking, your understanding, or the prospects in the long run of avoiding war.
