Today I saw his has-been ugly face appear on Fox News TV and channel surfed elsewhere by a sheer impulse that instantaneously transpired.

Good job there, mc. I find the hysterical laughter t the end being most certainly borne by your utter grief to be quite poignant.

I'd like to make The Bee funnier. Don't post most here due to that.

All of the stuff they're concerned about is a mix of very inert, lead-like (and actually heavier!) Uranium 238 and more unstable, somewhat radioactive Uranium 235. Remember those numbers: 238 & 235.
the depleted uranium that our military uses in cannon shells is practically pure 238, because it's heavier than lead and practically non-radioactive. Pure U-235 is dangerous in large amounts - if you get more than 52 Kg / ~100lbs (or less, if you surround it with neutron reflectors) together, it can go critical, with city-leveling results.
The amount needed depends on how refined it is, which is why they need huge centrifuges to separate it out. Consider that you have two versions of the same metal, mixed, where they are chemically ~identical~, and you're trying to separate out the atoms that weigh 1.3% more than the others. Fun. So, the slightly enriched stuff is almost all 238 and therefore almost inert. The good stuff has more 235 but is progressively harder to produce as you increase the purity, i.e. the percentage of U-235. The power-reactor grade stuff is not near as pure, which should have been enough for the Iranians, ~if~ they were only going to use it in power reactors. From Wikipedia: "Naturally occurring uranium contains only about 0.7% U-235. To be used in most nuclear reactors, the uranium needs to be enriched to a higher concentration of U-235, typically 3-5%. For weapons, enrichment levels of 95% or more are needed".
The Ayatolla's shiites (or Shinolas, I can't ever tell which) were concentrating far beyond reactor grade, thus they were attempting to build bombs, and needed to be taken out.
Fortunately, the few hundred pounds they may have had of "the good stuff" is now buried (and shielded!) under millions of tons of granite rubble, and so is fairly safe for the foreseeable future.

That's what this dino been thinking.
Maybe volunteers to die for Allah can be scrounged up to dig back into what's been blown up to start reconstruction.
That way all those heroes can each wake up in hell with 72 dead virgins.
