number is some or none as long as the killing continues. The Middle East over the last more than 100 years has been one of the biggest jobs of gaslighting known to mankind. The big media never talk about the backstabbing and double dealing the British and French engaged in ala the Sykes-Picot Agreement and the McMahon-Hussein documents and all that surrounded those things and what came after. They don't talk about the backstabbing and double dealing by the British, French and US after WW2 regarding there true goals and aims.
Suffice it to say that there is every good reason for people to spit on the ground when they hear the US, British or French talk about how they want to act as "honest mediators". But if someone doubts the dishonest conduct of those nations all one needs to do is ask the Irish about how reliable the words or integrity of the British are regarding any agreement or assurances. Ask the indigenous people of America what the word or integrity of the American government is once they make an agreement and give assurances.
The British, French and the US were looking out for their own interests and control in the Middle East and the lives of the people there didn't mean jack-shit to those countries and they still don't. It is still about oil,money and control for those countries as far as the outcome each wants. But they keep exerting their influence while playing the tired charade of caring about the people when people stopped believing, with good example and reason, long ago that any of these parties could be trusted in anything they say or represent.
Two good works to read about this all are "A Line in the Sand" by James Barr which covers the period of 1914-1948 and the Sykes-Picot Agreement/Anglo and French conduct and then also "Lords of the Desert" also by James Barr which covers the period from 1941-1967 and the British and the US fighting each other for control and influence in the Middle East. Some people may think this history doesn't matter but the elimination of all vestiges of Sykes-Picot and it's lasting effects are a main battle cry for some of the Islamist militia groups and that goes beyond the issue of Israel alone.
So it does matter to know how it came about, how people lied, the arrogant actions of old Colonial powers and how media or governments today trying to ignore it all like it never happened is simple cowardice in leadership. Instead of owning up to what was done we get a Western media that acts like the only issue of conflict in the Middle East is just Israel and the Palestinians in the West Bank and Gaza and the hostility of Iran. They treat Syria like it was a sideshow opportunity for the major powers to trot out their latest military hardware and that it all boils down to Assad. It is colossal malfeasance for Western media and governments to portray a picture as though if Assad in Syria, the Islamic regime in Iran were gone and Israel were to be normalized by the Arab countries like Saudi Arabia that everything is then cool and groovy. It would still be far from it.
We in the US have our own clear examples of disingenuous conduct. For example we still have a government that when faced with treaty violations, failure to compensate for resources as promised etc. forces the Tribes to go through lengthy expensive litigation in court rather than simply being honest and owning up to the violations and making them right. The US position regarding those treaties can be summed up as "We will only honor what you force us to." Hardly a ringing endorsement for the idea of trusting such an entity in any proceedings of any kind.
