There are immense political differences in Libya and very petty internal rivalries between members of the same groups. This was clear from the birth of the Transitional Council in Benghazi. In effect this is what the US and its allies wanted in Libya from the start. They wanted a divided opposition to Muammar Gaddafi’s government that would only stay united under the control and management of the US, NATO, and the Arab sheikhdoms. The reason for this was that Washington could neutralize any Libyan opposition group that would get out of line by using the others against them. Moreover, if the new political leaders of Libya refuse to listen to Washington then the Americans can make them fight one another.
From Bosnia to Iraq and Afghanistan, wherever the US goes it deliberately creates a fragile political order that can be manipulated and upset from the outside. This way America can maintain influence over these countries by attempting to hold the balance of power between the rival groups."
And you wonder why Muslims are so pissed off.
