Really? I'll have to google that. However, I was primarily talking about taking a sample of the actual weapon primaries, then comparing those to the database of known sources. Apparently every legitimate production source is sampled since the chemical makeup of each uranium and plutonium charge is distinctly different (with precision measurement, you can find differences in the percentages of Thorium and other natural products of fission). In effect, any nuclear charge has a
fingerprint which reveals where it was made and enriched.
If sampling of Israel's warhead primaries shows no match to the databases of America and Russia, then I'll eat my hat.
