Obama is worried about nuclear proliferation in the Middle East
During his interview with Jeffrey Goldberg, President Obama made his case for why it was in the U.S. interest to deny Iran a nuclear weapon:
'If Iran gets a nuclear weapon, I won't name the countries, but there are probably four or five countries in the Middle East who say, "We are going to start a program, and we will have nuclear weapons."'
I think he's right, but consider the implications of that for a minute. The biggest danger of a nuclear Iran is... America's own "allies" in the Middle East.
