Donuel the reality is that the original thread title revolved around seemingly unsubstantiated allegations of initially novichok and later Douma. Unfortunately you cannot even begin to seek the truth without unraveling the history of the Middle East at least since the fall of the Ottoman Empire and the machinations of Empire post WW1. There are at least six components of the present chaos and a little digging would throw upp many others.
1)The geographic/political boundaries are largely artificial constructs
2)Between 25 and 35 million Kurds inhabit a mountainous region straddling the borders of Turkey, Iraq, Syria, Iran and Armenia. They make up the fourth-largest ethnic group in the Middle East, but they have never obtained a permanent nation state.
3)There are religious divides between Sunni and Shiites
4)Energy sources and their distribution networks bring in competing interests.
5)"Terminology on terrorist attacks are often misleading and the resulting danger to the Middle East often misunderstood. The Islamic State and its so-called provinces mimic quasi-states and insurgencies—
the terrorism label obfuscates much of the groups’ practices. The Islamic State and related groups use terrorism, of course, but they also wage insurgencies, control territory, and otherwise shape the region beyond terrorist attacks. These actions are often far more dangerous and consequential than terrorism."
6)Arms sales e.g. UK UK arms sales 2015-16. Saudi Arabia: £3.3 billion. United Arab Emirates: £265 million. Turkey: £175 million. Qatar: £139 million. Israel: £105 million. Oman: £71 million. Egypt: £65 million. Jordan: £19 million. Bahrain: £19 million. Kuwait: £13 million. Lebanon: £2.8 million. Yemen: £266,000 ... others dispute the figures as way too low.arms sales Now if anyone can unravel the true story of what is really happening in Syria they may well have a very good explanation as to why Russia, Assad and Iran are being constantly demonized. In my view it is a devils brew and Israel and her rogue attacks may well be the detonator to create a global war. It is a country in defiance of innumerable UN resolutions and takes zero notice of the International community.
