There must be many Syrian people who have PTSD. Those in Gaza too for sure as well as many ,many other people in the ME.
If PTSD means 'post-traumatic stress disorder', it is natural to have it where/when there are wars and terror.
Between year 1981 and 2010, there was no reason for most Syrians, if not all, to have it. Assad, father then son, were submitted totally (under the table, of course) to the will of the US system. Therefore, there were no wars between Syria and Israel (though Israel was always given the right to bombard Syria under various pretexts, as it is the case now). Yes, there was a war in year 1973. Its goal, on the Syrian side, was to clean the Palestinian military presence at the south of Syria (the Palestinian militants were moved to the south of Lebanon), also to give the Syrian Jolan (heights) to Israel. On the Egyptian side, it was to open the Suez Canal for Israel and Europe.
I used to think that PTSD could be seen among the soldiers only during or after wars; for example, as it happened to many American soldiers who were in Afghanistan and Iraq (lately, among the Israelis soldiers).
For instance, a kid, Muslim or Jewish, who is raised to serve his Allah or Moses' God, has no reason to have PTSD. He just does what he is ordered to do in the name of his god with proud... killing, stealing or whatever.
