This is a portion of an assessment of the alleged April 4, 2017 chemical weapons attack in Khan Shaykhun, Syria by MIT Professor Theodore A. Postol. The full assessment, published in the Unz Review, can be found here.

Dear Larry:

I am responding to your distribution of what I understand is a White House statement claiming intelligence findings about the nerve agent attack on April 4, 2017 in Khan Shaykhun, Syria. My understanding from your note is that this White House intelligence summary was released to you sometime on April 11, 2017.

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.

In fact, a main piece of evidence that is cited in the document points to an attack that was executed by individuals on the ground, not from an aircraft, on the morning of April 4.

This conclusion is based on an assumption made by the White House when it cited the source of the sarin release and the photographs of that source. My own assessment, is that the source was very likely tampered with or staged, so no serious conclusion could be made from the photographs cited by the White House.

However, if one assumes, as does the White House, that the source of the sarin was from this location and that the location was not tampered with, the most plausible conclusion is that the sarin was dispensed by an improvised dispersal device made from a 122 mm section of rocket tube filled with sarin and capped on both sides.

The only undisputable facts stated in the White House report is the claim that a chemical attack using nerve agent occurred in Khan Shaykhun, Syria on that morning. Although the White House statement repeats this point in many places within its report, 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.

The report instead repeats observations of physical effects suffered by victims that with very little doubt indicate nerve agent poisoning.

The only source the document cites as evidence that the attack was by the Syrian government is the crater it claims to have identified on a road in the North of Khan Shaykhun.
