That may have made sense in the 1950s and 1960s, when the outlines of the non-proliferation regime were first established.
A nuclear-armed Iran would be a disaster for international stability and the non-proliferation regime.
And withdrawing from the non-proliferation Treaty or kicking out U.N. nuclear inspectors would implicitly do the same thing.
The principle was crystal clear: non-proliferation for others means disarmament for us.
No non-proliferation among nuclear have-nots without serious commitment to eradication by nuclear haves.
It risks triggering a nuclear-arms race in the region, and the unraveling of the non-proliferation treaty.
This would reduce the threat that Iran could use the uranium for a nuclear weapon and give time for non-proliferation talks.
