Oak Ridge won't sell enough Po-210 in sum in any 140 day period to make a single atomic trigger, no matter what your credentials.
Iran's reactor isn't working yet; it is a non-entity for all *existing* weapons.
North Korea is grappling with the technical hurdles in making enough Po-210 fast enough for their own nuclear test. Frankly, my money says that Iran will have a successful nuclear test before North Korea and that neither will be able to test this year.
So there's a prediction that you can fact check me on over the next 5 months. I'll be right while you are still in wide-eyed panic.
I'm not the one panicking in denial.
Iran has already produced po-210, in case you didn't know. That isn't the hard part. The argument as to whether Iran or North Korea will be first to detonate a nuclear weapon is just another straw man to help you try to hide the FACT that you can't support your position. I haven't got a dog in that fight.
You have your head in the sand, trying to pretend that the barbarians are too stupid to copy our 60 year old technology.
