The Neocons/Zionists may get their war against Iran soon under Obama or in a few years’ time. Theirs is a decades, perhaps centuries-old plan to destroy Israel’s perceived historical foes.
Remember Wesley Clark’s admission about the Bush admin plan to bring down the governments of perhaps a dozen Arab/Muslim nations in the aftermath of 9/11?
The foundational stories and the history of Israel revolve around civilizational conflicts with the empires of Babylon, Sumer, Assyria, Egypt of the pharaos, Persia … i.e. present-day Iraq, Lebanon, Syria, Iran. They all must be laid to waste to fulfill Zio/Neocon dreams of vengeance.
Add to that the Christian Zionist wet dream of Armageddon and Israel shining upon the nations at the end of times and you can understand what drives these people.
