Argument: NATO has wrongly shifted from being defensive to offensive
Rep. Ron Paul, MD. "Against NATO Expansion". Lew Rockwell. 2004 - More than 50 years ago the North Atlantic Treaty Organization was formed to defend Western Europe and the United States against attack from the communist nations of Eastern Europe. It was an alliance of sovereign nations bound together in common purpose – for mutual defense. The deterrence value of NATO helped kept the peace throughout the Cold War. In short, NATO achieved its stated mission. With the fall of the Soviet system and the accompanying disappearance of the threat of attack, in 1989–1991, NATO’s reason to exist ceased. Unfortunately, as with most bureaucracies, the end of NATO’s mission did not mean the end of NATO. Instead, heads of NATO member states gathered in 1999 desperately attempting to devise new missions for the outdated and adrift alliance. This is where NATO moved from being a defensive alliance respecting the sovereignty of its members to an offensive and interventionist organization, concerned now with "economic, social and political difficulties...ethnic and religious rivalries, territorial disputes, inadequate or failed efforts at reform, the abuse of human rights, and the dissolution of states," in the words of the Washington 1999 Summit.
And we saw the fruits of this new NATO mission in the former Yugoslavia, where the US, through NATO, attacked a sovereign state that threatened neither the United States nor its own neighbors. In Yugoslavia, NATO abandoned the claim it once had to the moral high ground. The result of the illegal and immoral NATO intervention in the Balkans speaks for itself: NATO troops will occupy the Balkans for the foreseeable future. No peace has been attained, merely the cessation of hostilities and a permanent dependency on US foreign aid.
