Iako se Bush i de Hoop Scheffer pažljivo izražavaju kad su u pitanju predviđanja, nezavisnost Kosova i naknadna reakcija Srbije predstavljaju jaku motivaciju da se te tri zemlje jugoistočne Evrope uključe u Alijansu, jer bi se njihovim učlanjenjem u NATO značajno ojačala stabilnost u tom regionu.
Even though Bush and de Hoop Scheffer are being careful with their predictions, Kosovo's independence and Serbia's subsequent reaction are a strong motivation to include the three Southeast European countries in the Alliance, as their NATO membership would significantly boost stability in the region.
