Subject: Mattis 'No Doubt' Stance on Alleged Syrian CW Smacks of Politicized Intelligence

Donald Trump's new Secretary of Defense, retired Marine General James "Mad Dog" Mattis, during a recent trip to Israel, commented on the issue of Syria's retention and use of chemical weapons in violation of its obligations to dispose of the totality of its declared chemical weapons capability in accordance with the provisions of both the Chemical Weapons Convention (CWC) and relevant U.N. Security Council resolutions.

"There can be no doubt," Secretary Mattis said during a April 21, 2017 joint news conference with his Israeli counterpart, Minister of Defense Avigdor Lieberman, "in the international community's mind that Syria has retained chemical weapons in violation of its agreement and its statement that it had removed them all." To the contrary, Mattis noted, "I can say authoritatively they have retained some."

Lieberman joined Mattis in his assessment, noting that Israel had "100 percent information that [the] Assad regime used chemical weapons against [Syrian] rebels."

Both Mattis and Lieberman seemed to be channeling assessments offered to reporters two days prior, on April 19, 2017, by anonymous Israeli defense officials that the April 4, 2017 chemical weapons attack on the Syrian village of Khan Shaykhun was ordered by Syrian military commanders, with Syrian President Bashar al-Assad's personal knowledge, and that Syria retained a stock of "between one and three tons" of chemical weapons.
