What are the alternatives to NATO peacekeepers in Ukraine?

While NATO peacekeepers on the ground in Ukraine likely won't happen due to Russia's opposition, KT McFarlane suggests there are viable alternatives. Instead of NATO members, peacekeeping forces could be formed from countries around the world that are not part of the NATO alliance. These international forces could serve as a buffer between the conflicting parties, providing a peacekeeping presence that might be more acceptable to Russia than NATO forces. This approach acknowledges Russia's concerns while still offering a pathway to maintain stability in the region.
