Friedman highlights the importance of an interview with President Obama by Atlantic magazine's Jeffrey Goldberg. In this interview Obama gives a thoughtful understanding of what it means if Iran acquires nuclear weapons. The greatest danger is in nuclear proliferation. Obama brings to this an understanding of this issue from the time he focussed on this issue as a student at Columbia University, when he described the risks of nuclear proliferation in the Columbia student newspaper. There is the risk of an escalation in the development of nuclear weapons in the Middle East first, and then elsewhere. And there is the risk that nuclear weapons fall into the wrong hands. The situation would create problems like that faced in North Korea or in the India-Pakistan region, but increased by many times the current dangers. The entire nuclear de-proliferation effort and the efforts to de-nuclearize weapons stockpiles that took decades to accomplish with the Soviet Union could come undone- and it would then be necessary for all countries to invest in advanced technologies for defending against nuclear weapons, setting in motion another arms race. The current situation reminds people that the issues raised by nuclear weapons development will always be with us, and require a worldwide concerted effort, at official and public level, bringing in scientists, public opinion worldwide, and educating the public in all countries of the larger danger to mankind. The issues need to be put in the right context beyond nations and politics, beyond international conflicts and competing interests or ideologies, including Israel, Iran and any other nation looking for nuclear weapons as a solution for conflicts. Shultz, Perry, Kissinger and Nunn after a series of meetings at the Hoover Institution called for the update of the old policies of nuclear deterrance based on mutually assured destruction used with the Soviet Union, to reflect the new threat of terrorism- in an op-ed NYT 3/7/2011. The focus of this effort is on a new Fissile Material Cutoff Treaty, with all nations giving up nuclear material to an international nuclear material bank. Senator Obama strongly supported the efforts of Senators Lugar and Nunn in de-proliferation work after the collapse of the Soviet Union and joined the senators on one of their trips- Broad and Sanger, NYT, 7/5/2009. A major effort to reduce NATO, U.S. and Soviet nuclear weapons is called for to lead by example, providing a framework for other means of settling regional conflicts and educating public opinion in these countries, and moving forward the negotiating of the Fissile Material Cutoff Treaty. In many ways public opinion will have to lead the way in all countries as governments can lag behind- the efforts of Sam Nunn and Dick Lugar and the many unnamed people in the Soviet Union who aided their efforts show the importance of this....
