The reality on the ground was rather different, as Ylber Hysa has noted. Although "Resolution 1244 respects the sovereignty and territorial integrity of the Federal Republic of Yugoslavia, including Kosovo", and even provided for Serbian troops to be stationed in the province, on the ground "certain territories are under the full control of KFOR and the international administration" without any Serbian involvement. However, this part of the resolution was never implemented. The severely circumscribed control exercised by Serbia in Kosovo has led many commentators to describe the nature of its sovereignty as purely "nominal".
