Declare and urge world wide governments to declare the MB organization as terrorist group

Since they have been created 80 years ago, the Muslim Brotherhood organization have been creating and causing all kind of problems in Egypt and other countries; assassinations, bombings, torturing, Etc ...
Recently, they have been the main creators of chaos all over the middle eastern countries including close allies of the United States of America. I, ask and urge Mr. Obama's administration to declare the MB organization as a terrorist group and stop supporting them in any means necessary and urge worldwide governments and world wide openion to declare them as a terrorist group.
