According to this Uprising Map in the Middle East it looks like Iran and the Islamic terrorists under the guidance and authority of the Muslim Brotherhood that they are securing strategic key hold of entrances of the Suez Canal.
All of the uprising in the Middle East did not just happen like that. It was a man made force who incited them as well as supporting them. My hunch is that Iran under the guidance and authority of the Muslim Brotherhood group has incited and nurtured the events to fulfill their own ambitions of conquering and dominating the entire world including the USA.
Egypt and Yemen are key strategic points to control the flow of oil and military transport to the Islamic Republics.
What is astonishing is that the Obama administration is mum on this and maybe even unaware of it. With an administration whose only interest and work at this time is to be reelected. Obama has bought changes that you better believe will destroy the United States of America.
