>>507664966 (OP)I'm pretty sure they already have shitty nukes.
Like, you don't need anything fancy to get critical mass.
Sure if you want something fancy that you can actually put on a ICBM warhead, you need to get creative, cheat the critical mass by using highly syncronized pressure waves from conventional explosives, other fissile materials like plutonium you can only breed in reactors etc.
But if you just want big boom for the sake of big boom, all you need to do is create two large half-spheres of enriched uranium and slap 'em together.
And unironically even some shit-tier terrorist organization like ISIS could probably manage that if you give them two decades and $100 million in funding, so If Iran doesn't have enough enriched uranium even now when Bibi said they've been trying to build a bomb for the last 3 decades that'd be really fuckin pathetic.
So honestly If I was Iran, Id have done a shitty bomb test years ago and just claim its the real deal.
All the other nations could see the test on their Seismographs and can only conclude "yup, I ain't no clue what they got or how it works, but they sure got somthin that makes a boom with nuke-like amounts of TNT-equivalent", I don't think anyone would do the gamble and try to call the bluff that their nuke tech sucks dick and doesn't actually fit on an ICBM warhead.
