A study group at the Washington Institute for Near East Policy sends a public letter to U.S. president Obama on the Iran negotiations. It says the nuclear agreement negotiated with Iran "may fall short of the administration's own standard of a 'good' agreement." It is signed by some of Mr. Obama's main advisors during the first term. Some of these officials told the NYT that the letter was the result of serious concern that Mr. Kerry and other negotiators were moving towards major concessions that would weaken the international inspections of Iran's facilities, back away from making Iran reveal suspected past work on weapons, and allow Iranian R&D to move ahead with making nuclear fuel once the accord expires. The five Obama advisors from the first term who signed the letter are: Dennis Ross, Middle East negotiator, David Petraeus, CIA director, Robert Einhorn, State Department proliferation expert, Gary Samore, chief advisor on nuclear policy, Gen. James Cartwright, vice chairman Jt. Chiefs of Staff. Gary Samore is president of the advocacy group United Against Nuclear Iran. The letter was also signed by President Bush's national security advisor during his second term, Stephen Hadley. Such a large group of advisors to presidents Bush and Obama familiar with the details of Iran's development of nuclear technology and weapons capabilities could give Republicans support to kill any agreement that falls short on inspections during Congressional Review. On this key factor where only vague assurances are made by the Iranian side- such as signing an International Atomic Agency convention giving inspectors broad rights to visit suspicious sites, followed by Ayatollah Khamanei ruling out military sites- the letter is specific. Inspections it says " must include military (including Islamic Revolutionary Guards Corps), and other sensitive facilities. Iran must not be able to deny or delay timely access to any site anywhere in the country." Inspections work rigorously done is set as a precondition before any significant relief from economic sanctions on Iran....
