I thought Carter gave the technology to the Israelis and they have about 200 of them in stock.
IIRC, he also helped the French complete and test their own neutron bomb.
Most nations that tinker with that particular weapon design tend to be very vague as to its existence or quantity. It is truly idiotic to have that arrow in your quiver, then willingly throw it away like Bush 41 did. Very foolish.
Israel has (according to rumor) several hundred nuclear warheads, perhaps even a thermo warhead or several, but no neutron weapons.
Only China has that type of weapon fully field tested - just ask around in the muslim villages in the western provinces about why they are so peaceful toward the Party and the PLA. They don't want to be sent the message for the third time ...
Something like 800 warheads in the Israeli armory, some of them neutron bombs and some, it is said (but not confirmed) tactical nukes with some *directional* options. They can cauterize the whole of the ME in very short order.
