Even supposing Iran developed a nuclear weapon, their ability to engage in nuclear retaliation depends on (a) the number of warheads, (b) the available delivery mechanisms

An Iran which had only a handful of warheads, and rather limited delivery mechanisms (few or no ICBMs, no SLBMs, no long-range bomber capability) might find its ability to engage in nuclear retaliation against the US extremely limited

Even attempting to use nuclear weapons against Israel or regional US allies, there would be a massive attempt by Israel/US/allies to intercept any nuclear armed missile before it reached its destination

People argued missile defence (as in Reagan's "Star Wars") would never work against the Soviets because they could always just overwhelm it given the superabundance of warheads and delivery systems they had. The same logic does not apply to Iran, because even if it did build a nuke, initially it would only have a handful. Only if they were allowed to build out their nuclear arsenal and delivery systems without intervention, over an extended period, might that eventually come true.

The symbolic value of Iran hitting a target in the US, even with only a small conventional warhead, would be considerable. Washington, D.C. has some drone and missile defenses. But the rest of the east coast is not protected much.

Iran could also attack the US with drones launched from a small ship off the US east coast. Roughly the same technique Ukraine just used on Russia, using some small expendable ship instead of a trailer.

It led Iran to make 2 decisions

- Accelerate production of IRBM in order to have 10000 in stock and to build 1000 launchers in order to execute massive launches that will not possible to defend against

- Apparently the did decide to mate their IRBM with nukes as recently there was meeting between whoever managed iranian missiles problem and heads of nuclear project (there is economist article about it).

This comes against backdrop of hamas and hezbollah been wiped. especially hezbollah which was supposed to be strike force against israel with estimated 100k-200k missiles and rockets.

PS. to those who write that jordan/usa intercepted most/a lot. they (together with saudi arabia, uk and france intercepted drones and cruise missiles. out of all IRBM only 6 were intercepted with SM3 missiles from USA ship)

I wonder if anything started happening recently that would make Iran less interested in cooperating with the IAEA?

In fact, I think all evidence points to them removing assets from inspected sites knowing that those sites would soon be targets.

> Just explain why you have 60% enriched uranium.

For leverage, obviously.

If Israel were Iran's only rival then it would obviously do everything in its power to become nuclear capable because Israel violated international law to become nuclear capable. However, Iran has many rivals and does not want to set off a nuclear arms race in the middle east.

They also hoped to use the nuclear program as a bargaining chip to lift sanctions.

So Iran had reason to set themselves up to be able to get nuclear weapons, without actually getting nuclear weapons.

Now, that whole policy looks foolish and Iran's only real rational option is to acquire nuclear weapons as quickly as possible.
