Professor Theodore Postol, professor emeritus of science, technology, and national security policy at Massachusetts Institute of Technology, issued a 14-page document on April 11, refuting the 4-page “dossier” issued by the White House the day before, which supposedly proved that the government of Bashar al Assad was responsible for the April 4 chemical weapons attack in Khan Shaykhun, Syria..
Two days later, Prof. Postol published an addendum to his document. He is the expert who, in 2013, proved that the apparent use of chemical weapons at that time was not done by the Syrian government, but by rebel groups.
“I have reviewed the document carefully, and I believe it can be shown, without doubt, that the document does not provide any evidence whatsoever that the US government has concrete knowledge that the government of Syria was the source of the chemical attack in Khan Shaykhun, Syria at roughly 6 to 7 a.m. on April 4, 2017.”
The evidence that is available, he reports, suggests, in fact, that the attack was executed by individuals on the ground, and not from an aircraft. Postol’s own assessment of the imagery used to draw conclusions about the source of the gas is that it “was very likely tampered with or staged, so no serious conclusion could be made from the photographs cited by the White House.”
Although the White House statement notes repeatedly that a chemical attack using nerve agent occurred in Khan Shaykhun, the report contains absolutely no evidence that this attack was the result of a munition being dropped from an aircraft. In fact, the report contains absolutely no evidence that would indicate who was the perpetrator of this atrocity.”
Postol’s report makes use of Google Earth and other images, diagrams, and detailed analysis of the photographs provided by the White House.
