The grain crisis has been resolved for now. Turkey's mediation softened the atmosphere. A way of salvation has been opened for people who are in danger of a grain crisis. Also, normalization in grain prices started after this diplomatic initiative. I call it a good day for humanity.
https://youtu.be/JXjO_nohjCkI wouldn't jump into conclusion that everything is resolved just like that, specially since Erdogan was brought to Iran to be reprimanded and considering that he has lost everything in the new world order and he was threatening to destabilize Syria and Iraq a bone had to be thrown for him to bite on for the time being.
Nevertheless, this was a small positive news ~2 weeks ago.
There is no need to look for deep meanings under this beautiful step taken in the name of humanity.
Türkiye is a self-sufficient country in grain production. If Turkey wanted to, it could turn its back on this problem. But this behavior would not be good behavior for the rest of the world. Also, Türkiye is the only country that can have diplomatic relations with Russia and Ukraine at the same time. We need to be able to talk to solve problems. So, whatever the problem, we should not close the channels of dialogue. Also, Türkiye is the only country in the region to fight terrorist organizations such as YPG, PKK and DAESH at the same time. These organizations have harmed thousands of civilians. They are the common problem of humanity. Türkiye cares about security in the region and is making efforts for it. Ships that will act under the control of Türkiye will follow a safe route. Russia and Ukraine have no doubts about this. As a result, there would be no better mediator for this problem.
