The Muslim Brotherhood has had a plan to infiltrate, undermine, and destroy Western Civilization since the 1980's. The plan is working pretty well in Western Europe. The Muslim Brotherhood also had a plan to strike the heart of Western Civilization in the USA. Many Americans refuse to believe that the Muslim Brotherhood represents a serious threat. They have had some success in the USA. They have established a lot of mosques, have elected Muslims to Congress, and have gotten a lot of schools to give Muslims special dispensation to do things that would not be allowed for Christians or Jews. And, they are no doubt encouraged by the election of Obama, whether or not that is reasonable. Here is an article about recent developments in the Muslim Brotherhoods attempts to undermine the USA.
