what exactly went on during the Nixon-Meir one-on-one meeting of 26 September 1969

"A draft Kissinger memorandum, declassified in 2007 and included in today's publication, sheds some light on why Nixon may have concluded that keeping the Israeli nuclear program a secret was the optimum solution. Certainly the outcome of the Nixon-Meir secret understanding-which left the Israeli program in place and secret-was significantly different from the recommendations of his key officials (not withstanding National Security Advisor, Henry Kissinger), but to this day we have almost no paper trail on the most important element in the policy puzzle: what exactly went on during the Nixon-Meir one-on-one meeting of 26 September 1969. Indeed, it appears that no record exists in the national archives of either country that reveals what was agreed to at the meeting."
