Bekaa Valley? Rings a bell doesn't it?
It will be difficult to force Syria from the Bakaa Valley because they control narcotics production in and through the area. It has been the cash cow for the Assad family for more than three decades.
Some say Saddam's WMD are in Bekaa valley.
If Assad brings them (back) to Syria, he risks getting caught with the 'goods'.
