I could break down hundreds of incidents where Turkiye was being screwed by the USA and Europe over the conflict.
The last rebel holdout was idlib, we were on the eve of an iranian, assadist and russian attempt to finish off the rebels and they began their onslaught on idlib. The russians even bombed Turkish troops in idlib killing at least 30.
For Erdogan and Turkiye, if idlib fell they would have lost everything but more importantly for erdogan it would have led to around another 5 million refugees entering Turkiye.
The atmosphere in Turkiye over the refugees had already reached breaking point. We had more refugees then the entire EU combined. If idlib fell and those people fled to Turkiye it probably would have been the end of Erdogans political career. You see many people in Turkiye were against the war in Syria, had he lost it and Turkiye got rewarded with a total of about 10 million syrian refugees, his career was over.
While this was happening Turkiye was being threatened by the USA not to do anything, but it was the EU that threatened economic sanctions against Turkiye if erdogan does anything to stop the assault. Basically another threat warning Turkiye not to enter. The situation was so bad for erdogan that he actually was moving/forcing refugees towards the Turkish EU border and forcing them to cross. Not because he wanted to but because the situation became so dire for his political career and geopolitically what would come in syria could be exceptional dangerous to Turkiye. He was basically telling the eurokunts if your going to threaten me, im not holding onto 10 million refugees, they will become your problem.

"Groups of refugees and migrants are heading towards the EU after Turkey said it would not abide by a deal to stop them reaching Europe.
Turkey's communications chief said the country had not received enough support in hosting millions of Syrian refugees.
Its decision followed a deadly attack on Turkish troops by Syrian government forces in northern Syria.
The incident sparked fears of a major escalation involving Turkey and Syria's military ally, Russia."
This was his only way to get europeans/nato allies not to f'k Turkiye for what was about to come.
Anyway Turkiye intervened and saved the last rebel stronghold, not only did Turkiye get no support from the USA, Europe, or NATO they effectively operated against Turkiye.
So the rebels were never meant to survive let alone win, the US and EU were doing everything to stop the one nation from taking action which could help them win and indeed in the long run did help them win.
But the nuance of what was going on in that war especially concerning Turkiye was never ever explained in any serious detail by the western media. It only worked to portray Turkiye as an enemy,
Even when Isis appeared on the scene, effectively crippling and delegitimising the syrian opposition, the media in the west and russian targeted Turkiye and even claimed Iran and Assad are allies of the west in the fight against Isis. Turkiye was painted as the creator and sole backer of isis, despite suffering the 3rd most terrorists attacks from isis after iraq and syria.
The syrian revolution was never meant to succeed and the only nation who could have seen it succeed Turkiye, was the one nation constantly undermined by all actors in the region. From west to east.
