Yaacov Amidror (about whom I wrote about a couple of days ago) was Netanyahu’s National Security Council (NSC) advisor.
Thomas Donilon was President Obama’s National Security advisor.
They worked together extensively on a number of issues, chief among them was the Iranian nuclear program.
On September 16th they got together at Harvard University and talked about their cooperation on the Iranian nuclear file, their differences over the current talks with Iran (especially sanctions), and what would happen if Iran rejects the deal.
Professor Gary Samore who is also at Harvard talked spoke from the audience as to why the Iranian supreme leader may ultimately reject such a deal.
You can watch the panel below. I highly recommend it.
