Zelensky says the Russian delegation in Abu Dhabi refused to discuss a ceasefire. That's all the Ukrainians really want from the fake negotiations: either some kind of "ceasefire in the sky" so we stop hitting them with missiles, or an unconditional ceasefire so they can rearm. However, an exchange of prisoners had already been conducted. Humanitarian concerns are the only thing these meetings are good at. Although they really do not require such splendor.
