If the HUR head says so, it is no surprise that ordinary Ukrainians are fleeing in thousands even from supposedly elite units like "Anne of Kyiv", French trained white flags, you know.
Socis poll published by UP
50.6% of Ukrainians want peace talks mediated by foreign leaders
19.5% - conflict frozen along the current frontline
14.7% - fighting till full liberation (1991 borders)
10.2% - fighting till the Russians are pushed back to the Feb 2022 line of contact
The latter option is what Ukraine would have secured, had it signed Istanbul agreements. Any deal feasibly achievable now or later will be far, far worse. Boris Johnson and Biden administration made sure Istanbul deal is derailed, reportedly.

My take is that Zelensky admin is preparing Ukranians for a peace deal. See eg Arestovich post today.
