"The Salafi-jihadis - with whom Washington, London and Paris were unashamedly in bed during their humanitarian bombing campaign - are based in Cyrenaica, eastern Libya. Some have come from Iraq. Some are shuttling back and forth to and from Syria, aiming to destroy yet one more secular Arab republic.
They include the heavily armed gang that attacked the US consulate - the self-described Imprisoned Omar Abdul Rahman Brigades, which surfaced only four months ago. Three months ago, hundreds of AK-47-equipped Salafi-jihadis held Benghazi hostage demanding sharia law."
The Americans are still in bed with the Salafi muslims. They come from Saudi Arabia, Qatar, Pakistan... The assassination of a Sufi Muslim (the soft branch of Islam) mullah in Russsia who tried to rally both branches for a peaceful relationship is an indication of what higher spheres want. Meaning the hatred between the two beliefs. It is interesting to notice that every time the U.S is involved in the secular country (as you well said it), it becomes a theocracy to the expense of the population. Does the U.S. really want them to become democracies? It is doubtful.
