You can be certain that many geopolitical analysts will be commenting on, and quoting from, this recent current article in the London Review of Books. Apparently The New Yorker, which formerly carried his articles, found his insider information too hot to handle.
Hersh seems to have insider contacts everywhere that give him confidential information, that is, except within the Obama administration. In the article he quotes a number of sources, particularly within the Joint Chief of Staff, who know that the administration's position against Assad runs counter to all intelligence reports. So, what is missing from Hersh's report is any information on the unknown 800 pound gorilla in the room: any insider reports on why the Empire's Chief Executive's office is pursuing so vigorously and consistently their anti-Assad crusade in spite of its own intelligence reports. (This is not the first time this has happened.)
Obama now has a more compliant Pentagon. There will be no more indirect challenges from the military leadership to his policy of disdain for Assad and support for Erdoğan. Dempsey and his associates remain mystified by Obama’s continued public defence of Erdoğan, given the American intelligence community’s strong case against him – and the evidence that Obama, in private, accepts that case.However it is not hard to figure out. I have offered an explanation many times in my commentaries. The Empire's capitalist masters, who are addicted to wealth and power, simply must pursue control of the world's resources and markets regardless of the many devastating effects on societies, causing climate destabilization, and posing the threat of a nuclear war.
