U.S. lawmakers' letters addressed to John Kerry , on the eve of the meeting of high-level NATO in the UK , is a strong message - both in terms of content as well as by the number of major signatories - to support U.S. Congress euro- Atlantic integration of Kosovo , including its membership in the NATO alliance , on the eve of the sixth anniversary of its independence . Most American efforts and initiatives in support of Kosovo in recent decades , originated in the U.S. Congress , the effort to finally constituted official diplomatic and military policy of the United States policy, which finally led to NATO intervention - s to liberate Kosovo from Serbian oppression and its independence six years ago and its diplomatic recognition . Although NATO military intervention in Kosovo was the first such intervention in almost 75 -year history of the Alliance , U.S. lawmakers rightly call the United States and NATO as a first step , Kosovo be granted land in Partnership for Peace program , clearly defining , as well as highlight U.S. Congressmen , the path that will lead to full membership of the Republic of Kosovo in the Alliance of the North Atlantic Treaty . This initiative shows that forty U.S. congressional protagonists in support of Albanians in Kosovo and the U.S. Congress may have changed over the decades , but it is clear that the support of the U.S. Congress and Kosovo Albanians is stronger than ever . Are they doing Kosovo and Albanians in general what belongs to them and what is required of them , to deserve this continued support , in order to accelerate faster integration of all Albanians in the Euro - Atlantic ?
