Ok, so the latest outrage that makes a few conservative friends of mind red faced with bulging veins is that apparently Obama has made a deal with Iran that will result in the country being able to increase their GDP by selling oil. In return, they agree to let the inspectors visit sites inside the country instead of guessing from the outside.
Letting Iran sell billions of dollars worth of oil in principle gives them more resources to build an atom bomb with, however, they would have to do it under the nose of inspectors or throw them out again and hope the world will be slow in re-instantiating sanctions.
My thinking is I don’t see the point. Ultimately, Iran needs a big pile of raw uranium and a chemical plant. They need a bunch of high speed centrifuges, lasers, or calutrons. All the basic ideas for how to build all of this stuff is readily available and the detailed knowledge to actually build it they can learn or buy, and already have.
Once they get enough of the pure U-235 in storage, they pretty much have it made. The last step for a basic A-bomb is a lot easier than the enrichment part. Sure, making hydrogen bombs with respectable yield would take a lot more work and probably require setting off prototype devices for testing, but a mere 15 kilotons is plenty if they intend to create a last resort against invasion…
All they have to do is sneak a 15 kiloton device into Washington DC. Go for 10+ major American cities if they have that many bombs. If they had well trained and well equipped commando teams, without single points of failure (lists of who the agents are, how they plan to get in, etc), I don’t see how they could all be stopped. There’s more schemes that would probably work than could fit into a paper encyclopedia. A few obvious ones - the USA border is not protected at all in many places, such as the Washington State coastline. Iran could purchase or hijack some ocean going yachts, registered under another flag. They would sail to an undefended section of coast, then sneak their 1 ton or so crude A-bomb ashore in a boat, then load it into a rented van and drive it to the target. If they were caught, they’d set the device off with suicide switches, and they would pick a route that would pass through many major cities on the way to the target. Once the bomb were loaded into the vehicle it would be sealed with anti-tamper devices, and there would be a sensor like in the movie Speed that would set it off if the vehicle were stopped more than 20 minutes or so.
You don’t need ICBMs to essentially ruin the civilized world. Am I about right about this, or am I off base? It seems to me that the reason Iran doesn’t have nukes right now (if they don’t…) is because they haven’t really made a full out effort. ICBMs, if just a couple were launched, can be intercepted, and an awful lot of stuff had to work. The rocket, the guidance, all that aerospace hardware, the compact nuclear warhead has to survive the launch, reentry, etc and still go off with full yield, you want H-bombs to maximize the effect of an expensive missile, and so on and so forth.
A gun-type U-235 device that is just Fat Man made with slightly more compact parts is something that almost any nation could build, OTOH…
