On Monday, a group of military personnel infiltrated Russian territory near the border town of Belgorod. These soldiers, of Russian nationality and belonging to two separate units, display fierce opposition to Vladimir Putin.

Moscow says it has totally driven them out or eliminated them. In reality, says Carole Grimaud, this raid would aim to end the war by establishing a "demilitarized buffer zone between Russia and Ukraine". A solution similar to that adopted between the two Koreas and which results in a cessation of fighting without ratification.
