Again, what seems to be missing in the press accounts is these points:
1) If you have 90%+ enriched uranium, you can make a bomb with a
simple gun trigger that requires none of the sophisticated engineering
of an implosion trigger. After Hiroshima, the whole world knows that
it works.

2) You have to be a little crazy to use a gun trigger unless you have
complete control of everything: a delivery system that allows you to
arm it at the last minute, far from the launch site, etc.

3) The Iranians appear to be a little crazy.

And the delivery system can be a shipping container with the bomb in
place long before the intended use.
