All arguments are going to go on deaf ears, unless you present the scenario of what happens if in fact Iran went through with a nuclear attack. The argument is far stronger from this perspective and it still doesn't change the fact that Iran is no threat. I've posted this on several threads before and I wanted to put together all of that information for you guys.
My credentials on Iran: I was 1 of 4 Primary Missile Defense Operators under PATRIOT assigned exclusively to counter the Iranian air threat. My unit was also the first unit to deploy to South Korea in 50 years.

Iran's Threat Potential: Iran does have various capabilities that do make it a fairly strong adversary. It's strength is predominately by air. Namely, a fairly strong Air Force and large arsenal of missile types. It is also assumed that they have UAV and cruise missile technologies. They have an Army, the Revolutionary Guard, but it is insignificant in comparison to its air capability.
Since we are interested in nuclear threat potential, we have to first identify how they would use a nuclear weapon.
1) We can rule out suitcase nukes for now, because the United States and Russia are the only countries whom have successfully made a nuclear weapon small enough to be carried by a person. Considering Iran has yet to create even a single weapons-grade warhead, its reasonable to assume that they are even further from having the technical knowledge to scale one down.
2) The only means therefore to make an attack with a nuclear weapon is by a missile capable of carrying a warhead. Iran's
missile arsenal consists of Shahab-1 through Shahab-6, Scud-B and Scud-C missile types and various other short range missiles. Most of these are IRBMs (Intermediate Range) and none are ICBMs (Inter-Continental). Iran currently has no ICBM capability. This rules out any potential they could launch a warhead at the United States.
Missile Defense Systems in the Region: All of the following is public record and UNCLASSIFIED, just so it is clear.
I know for a fact that PATRIOT, AEGIS, and Israel's Iron Dome is deployed in the region. Other systems that are likely to be active are MEADS, THAAD, Arrow-2, and Phalanx 1B. We have sold PATRIOT PAC-2 missile defense systems to Taiwan, Egypt, Germany, South Korea, Greece, Israel, Japan, Kuwait, Netherlands, Saudi Arabia, and United Arab Emirates.
I've created a very rough map highlighting the approximate locations and coverage of PAC-2/PAC-3 (PATRIOT) systems in the region. These reflect both U.S. and foreign systems. Keep in mind, this does not reflect ANY OTHER systems that are active in the region.
Range rings and locations are only rough approximations. Again, all public domain and unclassified. Foreign missile defense systems are reflected, but the number of systems emplaced is uncertain. This map assumes less systems than are likely active.
As you can see, Iran's missile capability is almost entirely isolated from being any threat to Israel.
In order for Iran to launch any nuclear payload at Israel, they would have to first defeat the missile defense systems in Iraq, UAE, Jordan, Kuwait, Israel, etc. Just look at line of sight from Iran to Israel and you'll see it's a foolish argument. Since there is no way for Iran to defeat these systems, their only option would be to overwhelm them. In order to do that, they'd likely have to launch their entire arsenal of missiles, which is essentially impossible due to the amount of logistics that would involve, without clearly setting of early warning WORLDWIDE.
We have great early warning systems that would allow us to send in our Air Force to take out most launch locations, prior to launch. These would primarily be the mobile launch platforms and any mobilization on the ground would obviously be identified by satellite. Emplacement of these mobile launch systems takes hours to conduct, allowing more than enough time to respond. Further, any missiles that are launched would then allow us to immediately identify launch locations we initially missed, so it is unlikely they could fire more than one volly from each location. This means that logistically, they not only have to beat our early warning systems, but they'd also have to launch from multiple thousands of locations.
If Iran Does Launch: Iran would obviously not launch the few nuclear warheads they would have from locations anywhere near its borders as they would not want these locations to be vulnerable to air raids. Therefore, these warheads would much more likely be launched from mid-country. This is an important fact and poses major challenges to Iran, because any nuclear payload launched from Iran has a very high probability of being shot down over their own country and would cause widespread nuclear fallout for IRAN itself. It would then be followed by probably the largest counter-offensive in human history by the United States and Israel.
Conclusion: Iran would have to be 100% suicidal to engage in such tactic. Doing so has nearly 0% probability of achieving anything but causing fall-out upon their own citizens and then being obliterated by a massive counter-offensive. This fact, armed with the above knowledge, shows that it is unreasonable to even entertain the idea that Iran would be so ridiculous to engage in such warfare. Even if you were to assume that they were entirely motivated by Islamic Radicalism to carry out Jihad, this hardly seems like any efficient manner to fulfill such means.
This is an ongoing side project of mine to piece together more details through public sources to round out a strong argument. I'm working towards a more formal presentation that can be used by the grassroots. I'm hoping someone might have a better way to get this publicized so that its more useful and reputable. I contacted Ben Swann to cover this argument, but I haven't gotten a response. If there is a lot of support to go that route, it might be worth going at him as a group.
