The Iranians are almost there. This is how they did it

The Times of Israel just published a frightening and detailed look at how Iran has come this close to building their nuclear arsenal.

Since the last century, Iran has been methodically pursuing the in-house capability of developing a missile-delivered nuclear bomb. The regime of President Mahmoud Ahmadinejad is now closer than ever — probably in the latter stages of perfecting an atomic bomb with a multipoint detonation mechanism, compact enough to insert into a Shahab-3 missile nosecone.

For years, the Obama administration, Western governments, the United Nations, and the International Atomic Energy Administration (IAEA) have been fully aware of the specific details of Tehran’s nuclear weapons program, down to the blueprints and names of the engineers. Whether or not Iran will complete the last leg of its decades-long journey toward a deliverable atomic bomb is still unknown. The difference in viewing the cannon is whether you are staring down the muzzle or observing it through a telescope from a perch 6,000 miles away. Israel is peering into the muzzle, hence its assessment is different than Washington’s.

Protracted multilateral negotiations, crippling international sanctions, and even elaborate programs of sabotage have delayed but not derailed the nearly autarkic program. Now the world teeters at the brink of a regional war with profound global ramifications because the threat may have been ignored too long.

Here are the four determining factors, the dynamics of which will govern whether Israel launches a preemptive attack against Tehran’s massive nuclear infrastructure.

Four technological achievements are key to completing Tehran’s nuclear weapon: 1) accretion of enough nuclear materials, highly enriched to 90 percent, to make the bomb; 2) machining that highly-enriched material into metal for a spheroid warhead so it can fit into a missile nosecone for detonation; 3) a trigger mechanism to initiate the atomic explosion at the precise moment of missile reentry; and, of course, 4) a reliable rocket delivery system to carry such a weapon.
