Understanding Obama

The following is a thought experiment: an attempt to understand the Iranian deal by way of logical speculation regarding the issues and facts as perceived by the Obama administration. I am assuming that Obama is not a Marxist/Islamist/Kenyan, consumed by post-colonial resentment and dedicated to destroying the Constitution and the United States. Nor a Black Nationalist anti-Semite, whose most important priority regarding Iran is to screw Israel. I am assuming he is a patriotic American who desires to be a historically great President. I believe he is unsentimental regarding Israel (neither pro nor hostile) – unlike Truman, Clinton and Bush II; more like Eisenhower and Bush I. I believe he thinks that starting a 3rd Middle East war with Iran would be criminally stupid and devastatingly harmful to the United States.
