From the following mixed report of Globalsecurity one can see how little the West knows of the real capabilities of the man who has already used chemical weapons against neighboring country Chad. Gadaffi is anything but stupid, and surely not the pro-western Mubarak who agreed to step down under US pressure.. The West should act with wisdom and decisiveness if wanting to eliminate the biggest real threat for Europe. Or perhaps Gadaffi is the necessary evil as everyone of the 10 horns?

Libyan leader Muammar Qadhafi has shown that he is willing and capable  of using chemical weapons and missiles against his enemies. In 1986 and  1987 the Government of Chad  accused Libya of using toxic gas and napalm  against central government forces and against rebel forces. Libya may  have used mustard gas [possibly Iranian-supplied] delivered in bombs by  AN-26 aircraft in final phases of the war against Chad in September  1987. The wind blew the agent back onto the Libyan forces.

A team of American and British intelligence officers spent  about two  weeks Libya in October and again in December 2003. US and UK  specialists invited to Libya said they found few surprises in Libya's  chemical weapons program. The US and UK learned that Libya had tens of  tons of mustard agent produced about a decade earlier, as well as  hundreds of 250-pound aircraft bombs capable of dispersing the mustard  agent in combat. During the visits, the team of US and UK inspectors  went to dozens of sites related to Libya's nuclear effort, chemical  stockpile and missile program. Libya revealed the existence of precursor  materials used to develop nerve agents. Libya had also conducted  experiments on the nerve agents sarin and soman. 
A small desert ranch near Tripoli, described as a turkey farm,  was actually a hiding place for hundreds of chemical bombs. The mustard  gas and nerve agents were stored separately. Libyans took American  inspectors right to them, but it was not a place the US would have  looked.
