Brussels, 26 Nov. (LaPresse) – "We know that Russia's mindset has not changed since the days of Yalta, when it viewed our continent in terms of spheres of influence. So we must be clear that there can be no unilateral partition of a sovereign European nation and that borders cannot be changed by force. If we legitimise and formalise the weakening of borders today, we open the door to new wars tomorrow, and we cannot allow that to happen." This was stated by European Commission President Ursula von der Leyen in her speech to the European Parliament plenary on the Ukraine peace plan.
