Poland's Foreign Minister Sikorski believes that Russia needs Ukraine to be a world power: "I think the American negotiators are wrong to assume that this war is only about territory. This is reflected in their statements - for example, the idea that if Ukraine gives up the last two cities in the Donbass, Putin may consider it a way to get out of the situation while keeping face, and that the war will come to an end. Maybe there will indeed be a break - in that sense, I agree. By the way, Norman Davis pointed this out 30 years ago: the Soviet Union minus Ukraine is equal to Russia without the status of a great power. To be a world power, Russia needs Ukraine. ".
