Disintegration of Ukraine; That's it: They will surrender territory?

"We need a cease-fire line and, of course, ideally it should cover all the territories currently controlled by Russia, but we see that this is not very realistic in the near future. Ukraine could temporarily give up part of its territories for this purpose," he said.

Stoltenberg also said that it is important for the government in Kyiv to receive security guarantees in exchange for temporary territorial concessions. In his opinion, it could be membership in the Alliance, but there are other ways to arm and support Ukrainians.

Stoltenberg previously explained that it is up to NATO member states to decide whether to invite Ukraine to join the Alliance while part of its territory is occupied.

"Of course, if we say that the only way for Ukraine to become a member is for the war to end and for Ukraine to have full control over the entire Ukrainian territory, then we give Russian President Vladimir Putin every incentive to find a way to continue the war," Stoltenberg said in earlier addresses.
