Western air strikes have done little to degrade President  Assad's arsenal and his regime has the capabilities of inflicting major damages .

Brigadier-General Zaher al-Sakat, who served as head of chemical warfare in the powerful 5th Division of the military until he defected in 2013, said the most strategic sites were not hit in Saturday's strikes .

The Pentagon said that it believed the raids " attacked the heart of the Syrian chemical weapon program " significantly hampering the government's ability to use gas weapon again .
