Who in the world wants stupid Kiev? Zelensky is there, and he couldn't take back the Black Sea Corridor. Besides, he got over half a million of his people killed for nothing. All Russia has to do is wait a little longer and the rest of the Ukrainians will be dead. Then Russia can just go in and take Kiev, but still won't. Who wants it?

That is FALSE INFORMATION, the Black Sea corridor has been in continous use by Ukraine. The grain exports have continued, while Ruzzia had to move nearly all the Black sea fleet out of Sebastopol and is under threat even in the further away ports in the Balck sea.
Ukraine took and holds "snake island" and has been systematically attacking the Ruzzian navy with sea drones. Ruzzia has clearly lost the Black Sea battle.

Few cargo ships dared to go to Ukrainian ports, and monthly grain exports fell to just over 2 million tonnes in July, August and September 2023.
Ukraine has since established new export routes.
Between the end of the grain deal in July 2023 and the end of February 2024, it shipped about 20 million tonnes of grain to 42 countries, according to the country's vice prime minister Oleksandr Kubrakov.
