In 2015, Ukraine put on the table a proposal for a UN peacekeeping mission, and it has always been on the table since 2015. I believe, frankly, that because there was a threat of the U.S. providing Ukraine with defensive military equipment, which the White House is very seriously contemplating right now, it's only very recently that Russia has tried to come up with their own version of a peacekeeping mission. It would essentially provide UN peacekeepers. They would be part of that UN peacekeeping mission. It is a little bit strange to have the aggressor as part of the peacekeeping mission on the border where the conflict is happening. Essentially, they would ensure a frozen conflict.
What Ukraine has asked for, and other European and allied countries have supported, is essentially having UN peacekeepers on the Russian-Ukrainian border to stop the flow of arms. There are hundreds of tanks in Ukraine that weren't built in the Donbass. Stop the flow of arms and soldiers into Ukraine. That would be step number one.
Step number two would be to have a UN peacekeeping force in that region, which it is hoped would essentially demilitarize that situation and allow for a return of those internally displaced peoples, a return to normality, and a stop to the bloodshed in Ukraine.
