Sharp asked Kissinger how the proliferation of nuclear technology could be prevented and what should be said to the Argentines and the Egyptians, who were also seeking to use nuclear energy. But Kissinger evidently had no answer.

The French had not given an answer and bilateral discussions would take place to go over the issues.
