The fact that July comes before August in my calendar is beside the point. Even if we agree that initially for like two months AKP didn't intervene (contrary to all the evidence, some of which you posted yourself, including the Erdoğan speech), this was all before U.S. active involvement. The problem with the policy was that it didn't foresee U.S. aims and goals, and used state resources and Syrian opposition in parallel to U.S. involvement, not in lieu of or despite them. If the analysis was correct that Syria is not going to change admin, but is going to be effectively partitioned, the resources and intervention (which lest the contrary be inferred from my side, I'm not against in principle, but in mode), would have been channeled accordingly. A higher level of cooperation with Russia, even backdoor deals with Assad could have been achieved. But it is obvious our admin's heads were in the clouds (captagon clouds if you will) of Muslim Brotherhood, rather than in the dusts rising off of YPG Toyotas (which we helped them get).
I think you seem to have not followed the Syrian war properly.
A few reminders for you;
- We brought the Assad regime to the point of exhaustion in 2013 (before Iran publicly sent Hezbollah to help).
- We brought Iran's Hezbollah to the point of extinction in 2015
- Russia came last. If Russia had not entered Syria, we would have already overthrown the Assad regime. When the Russians entered Syria, they made an alliance with both Iran and the USA (via the YPG) against us. Therefore, it was not Turkey's fault that the Assad regime had not been overthrown even though 4 years had passed since the start of the war.
In 2013, when the Assad regime was exhausted to the bone, there was no ISIS. DAESH emerged in June 2014. If we could not foresee the emergence of DAESH in 2013, Türkiye was not to blame.
Both Russia and the USA used ISIS to destroy groups supported by Turkey. Even when we directly intervened in the field with the Euphrates Shield, Iran-Russia and the USA made an alliance against us on YPG and ISIS. It was not Turkey's fault for not foreseeing that this would happen.
The 15-year acceleration occurred in 4-5 years. It was not Turkey's fault for not foreseeing that the USA would gift Syria to Russia. If the USA wanted, it could easily prevent Russia from landing in warm seas. But they did not want it.
Here we see that countries that would normally be at odds with each other if left alone have a common agenda against Turkey. It wasn't our fault that they had common agendas.
You should first sit down and reexamine the Syrian civil war.
