I am a hater of the US policies as much as any guy on this forum but lately America bashing has become so common that we have started to forget everything else.
Not to defend the US but looking back, this whole US-ypg mess is as much our fault as it is US'.
Back around 2012 when the international coalition to fight daesh was formed the US first came to us asking for help. They said "you are our nato ally and you have a 900 km border with Syria, you are the most effective factor against daesh and we need your help". But you know what we did? We refused. First we offered the hostage situation as an excuse (our embassy staff were taken hostage by ISIS). But then CIA helped us rescue those guys, and the US asked what now? You know what we did? You guessed it right. We refused to join in.
Then the US had no chance but to find another partner. And they found ypg. When it was too late we ran back to the US and asked them to stop what they are saying. But they said "you are an unreliable ally. You refused to help us when we needed your help. You made up excuses and even when we helped resolve those you still refused. We have moved on, we have a new ally now."
And to be frank they are at least partially right.
What we did was a strategic mistake. But it is time to let bygones be bygones and focus on the present.
By now it is clear that the ypg is much more important to the US than Turkey. This means that if the time comes to choose between Turkey and ypg they will choose the latter. This means Turkey has two options. Either we make peace with the situation, forget everything that happened, make friends with the US and ypg like we did with barzani and use the situation to our advantage. (remember, at least now that ypg has formed an entity we know where to hit when it comes to that) the second option is to burn the bridges, take all the risk and attack while we still have the chance. I doubt that the US will open war against us just because we attacked Ypg but I am sure that they will do everything else. We will be harmed big time, no doubt in that but at least we will have accomplished something.
Sorry for the long post
