the west and Turkey have an interest in removing Assad. Though our initial tool, fsa, has failed, it's all about IS, fsa has become a minor player it seems. However, even if Turkey stayed neutral, problems (more terrorists in the neighbor, refugees, destabilization etc.) would come towards Turkey anyway. imo It's better for Turkey to put its hand in the case and try to give the situation a swing in Turkey's favor. If Assad can be removed and a friendly pro-Turkey/western leader can be placed there, it would be a win. If that Russian base can be kicked out, it would be even better. if anything, at least Turkey will have avenged for all those years that Assad family supported pkk against Turkey in the 90's. the thing is, western countries are to blame too about fsa and the vacuum it left for IS, but they are far away from this mess, Turkey isn't. Turkey supported/supports moderate fsa, its no secret that these guys were helped by Turkey, but claims such as Turkey supporting IS doesnt make sense. they threatened Turkey, kidnapped Turkish truck drivers and Turkish diplomats (who are still their hostages), they killed Turkish cop/soldiers in Turkey before, IS is killing Turkmen too, Turkey wanted to stage a false flag in order to preemptively attack IS (there was even a leaked tape wherein the head of MIT, Turkish intelligence, and other high ranking people were discussing about this). quite many logical reasons, yet we are supposed to believe crap such as the OP.
my conspiracy theory for whatever it is worth; i still believe that IS is an US (maybe UK and Israel too?) project and used the FSA, hence they are suddenly silent and 'out of the picture', as a stepping stone to create vacuum for IS to fill up. If you look carefully, everything IS does, suits KRG and Israel. when IS started attacking krg, the US suddenly decided to intervene, provide weapons to the Kurds and launch strikes against IS. IS is temporary, what will remain is important, and i think an even more independent krg will prevail, much to the delight of Israel, which can use such a Kurdistan as a stepping stone (since air strikes from Israel are quite tricky due long distance) against Iran and buffer/ally against Iran and Arabs. Let also add the deafening silence of the oh so great caliph IS against Israel while the latter was slaughtering Palestinians The ME was redrawn by western countries before, why shouldnt they be able to do it again?
i agree with almost all your statements bro. However, i dont see any interests Turkey had in removing Assad. As far as i know, before this conflict started, Turkey was in very good terms with Assad/syria. Removing Assad will only lead to a power vacuum/collapse of the central government which will give even more space/arms/ammunitions/finance to ISIS and other islamic groups in the region, This is something i thought everybody knew including you. Just look at the situation in Libya now, it went from being African most wealthy(gdp per capital/living standards) country to been on its way to somalia a 'failed state'.
As for your coment about our governments being responsible, yes i absolutely agree with you about that. We are also responsible for the current situation/ISIS, due to our support to these groups in Syria. However i can understand our governments position, since we wanted to weaken Syria and by extension Iran/Russia(who has its only base in middle east there). So it made sense for us, seeing we had little interests in Syria anyway and we are far far away from the region..So we basically had nothing to lose. Unlike Turkey who is a middle eastern country and borders Syria. So of course i think Turkey should have thought things more carefully, its obvious that they shouldnt have supported/armed/provide transit/refuge the rebels in the first place, since this will obviously onlylead to more destablisation in the regiona and subsequently have a negetaive impact on turkey itself. I think Turkey made a bad decision. Hopefully, we can all redefine/revise how policies towards the region. Since i dont think ignoring working with Syrian government to get rid of these scums will solve the problem, we should work with them and admit we made mistake. if not things will only get worst.
