The International Community in the last decade repeatedly made a mess of handling the many demands that were made for "humanitarian intervention": coercive action against a state to protect people within its borders from suffering grave harm. There were no agreed rules for handling cases such as Somalia, Bosnia, Rwanda, and Kosovo at the start of the 1990s, and there remain none today. Disagreement continues about whether there is a right of intervention, how and when it should be exercised, and under whose authority. Since September 11, 2001, policy attention has been captured by a different set of problems: the response to global terrorism and the case for "hot preemption" against countries believed to be irresponsibly acquiring weapons of mass destruction. These issues, however, are conceptually and practically distinct. There are indeed common questions, especially concerning the precautionary principles that should apply to any:military action anywhere. But what is involved in the debates about intervention in Afghanistan, Iraq, and elsewhere is the scope and limits of countries' rights to act in self-defense-not their right, or obligation, to intervene elsewhere to protect peoples other than their own. Meanwhile, the debate about intervention for human protection purposes has not gone away. And it will not go away so long as human nature remains as fallible as it is and internal conflict and state failures stay as prevalent as they are. The debate was certainly a lively one throughout the 1990s. Controversy may have been muted in the case of the interventions, by varying casts of actors, in Liberia in 1990, northern Iraq in 1991, Haiti in 1994, Sierra Leone in 1997, and (not strictly coercively) East Timor in 1999. But in Somalia in 1993, Rwanda in 1994, and Bosnia in 1995, the UN action taken (if taken at all) was widely perceived as too little too late, misconceived, poorly resourced, poorly executed, or all of the above. During NATO's 1999 intervention in Kosovo, Security Council members were sharply divided; the legal justification for action without UN authority was asserted but largely unargued; and great misgivings surrounded the means by which the allies waged the war. It is only a matter of time before reports emerge again from somewhere of massacres, mass starvation, rape, and ethnic cleansing. And then the question will arise again in the Security Council, in political capitals, and in the media: What do we do? This time around the international community must have the answers.' Few things have done more harm to its shared ideal that people are all equal in worth and dignity than the inability of the community of states to prevent these horrors. In this new century, there must be no more Rwandas. Secretary-General Kofi Annan, deeply troubled by the inconsistency of the international response, has repeatedly challenged the General Assembly to find a way through these dilemmas. But in the debates that followed his calls, he was rewarded for the most part by cantankerous exchanges in which fervent supporters of intervention on human rights grounds, opposed by anxious defenders of state sovereignty, dug themselves deeper and deeper into opposing trenches. If the international community is to respond to this challenge, the whole debate must be turned on its head. The issue must be refrained not as an argument about the "right to intervene" but about the "responsibility to protect." And it has to be accepted that although this responsibility is owed by all sovereign states to their own citizens in the first instance, it must be picked up by the international community if that first-tier responsibility is abdicated, or if it cannot be exercised.
