In a video published by several Ukrainian media, Arestovich said the exact timing would depend on how much resources the Kremlin was willing to commit to the campaign.

“I think that no later than in May, early May, we should have a peace agreement, maybe much earlier, we will see, I am talking about the latest possible dates,” Arestovich said.

“We are at a fork in the road now: there will either be a peace deal struck very quickly, within a week or two, with troop withdrawal and everything, or there will be an attempt to scrape together some, say, Syrians for a round two and, when we grind them too, an agreement by mid-April or late April.”
