That's typical in mid Eastern countries where unfortunately dictatorships work well. Vacuums are created when they're removed. Libya is a great example after Khaddafi was deposed. The attack on Benghazi was actually three separate attacks by three different organizations. When the first attack failed, two other followed.
If we didn't have troops in Iraq, it would fall apart as it did Afghanistan whether Russia or American's were there.
In Benghazi, we were collecting and shipping weapons to Al Qeida in Syria, via Turkey, on the Saudi dime.
That was where we switched sides in the war in terror.
