It would also appear that this "deal" had been in the works for at least several months before the Geneva meetings. The Daily Beast reports: "The Obama administration began softening sanctions on Iran after the election of Iran's new president in June, well before the current round of nuclear talks in Geneva or the historic phone call between the two leaders in September."
The administration pledges to watch Iran closely and if it violates any provisions in a final agreement, sanctions would be re-imposed. If sanctions and other means, such as the introduction of the Stuxnet virus into Iran's computers, failed to deter Iran's nuclear program, why would anyone think additional threats and more sanctions would produce the desired results? Iran is playing for time and it appears the United States is willing to give it to them.
History is a great teacher, but not everyone pays attention. In "The Guns at Last Light," Rick Atkinson's chronicle of World War II, the author recalls President Franklin Roosevelt's view of Soviet dictator Josef Stalin following their meeting at Yalta in February 1945: "'Stalin doesn't want anything other than security for his country,' the president said. 'He won't try to annex anything and will work for a world of democracy and peace.'"
Winston Churchill similarly misjudged Stalin, writes Atkinson, telling his war cabinet, "'Stalin I'm sure means well to the world and Poland. ... He will not embark on bad adventures.' He added, 'I don't think I'm wrong about Stalin,' whom he had called 'that great and good man.'"
Times and dictators change, but human nature remains the same. Roosevelt and Churchill were wrong about Stalin and the Obama administration is wrong about Iran.
