The most important thing for any attack on a chemical weapons stockpile is reliable intelligence on where these weapons are hiding. Geospatial intelligence includes imagery from aircraft, drones, and satellites. In the past this has spotted activity associated with chemical strikes—seeing where chemical bombs loaded onto aircraft came from.
Western powers are to attempt to inject diplomatic momentum behind the military strikes against Syrian government chemical weapon sites by calling for the UN to launch a broad investigation into Syria’s chemical weapons stockpiles.
But the assessment also indicated that a large quantity of the chemical weapons was stored elsewhere and that Syria’s chemical weapons programme, while crude, “is about as good as it needs to be for Assad’s purposes,” another official said.
U.S., French and British forces launched 105 missiles from aircraft and ships at three chemical weapons facilities in Syria last weekend in response to a chemical weapons attack launched by the regime of Syrian President Bashar Assad.
