Just curious, what is wrong with Saudi Arab and Russia apart from American angle.
let me try to explain in short....
assad the president , belong to the minorities sect called alwati , this sect also has control in security forces.....
rest more then 85% polulation is sunni and kurdis.....
this was the begining of the conflict , protests was mainly peacefull in begining...
then comes the US angle , assad openly oppose US policies in iraq....he oppose the turky pipeline project which directly affects commercial intrests of turky.....
CIA start funding the rebles and gradually the political peacfull protest inside syria turn into armed conflict and mass voilation of human right from both sides....initially armed rebles wre the defection groups from syrian army but they are now overtaken by jihadies of IS....
now presently different parties involved in syria has their own angle of intrest....
russia : pro-assad stand , due to militery alliance....
turky: anti-assad due to commercial angle...
arab : anti-assad because assad is a sunni suppresser for them..
US/isreal/west : they want assad to step down for various geographical , commercial and security reasons...
i hope i summed up the syrian confilt to best of my understanding ....
rest there are more informed members out here to enlighten us more on the issue...
