As President Bush argued, the intervention set forth a mission to "to bring freedom to the Middle East, a freedom that wasn't "America's gift to the world," but "God's gift to mankind." (Smoltczyk and Zand, 2010) The dilemma appears from the fact that morality seats on rules, and these were not respected. If one would take as fair and moral for states to invade others that do not preserve international human rights, for example, the international system would transform itself into an anarchy. There is no higher authority that can identity those that are meant to exercise power over others as all is a matter of perception and information. If no such higher power exists, the international system has to adapt and create new types of morals. An ethics of nation building and re-building might be a solution, as episodes like the Iraq invasion might happen again. As Noah Feldman argues, the international system would need, in such cases a "nation builder [that] exercises temporary political authority as trustee on behalf of the people being governed, in much the same way that an elected government does." (Feldman, 2004)

Ethics change in time and they suit the needs of various societies...

Although it might look unethical to invade a country and produce the death of a significant number of people, from a different point-of-view this action could be seen as ethical. It could lead to the change of an authoritarian regime that produces destruction towards a people or different minorities.
The main questions still remain: was the Iraqi intervention just and moral? Is morality dependant on pre-imposed rules or can the ways of morality be changed to prevent or stop immoral things from happening? In this case, we would compromise over morality, which, in a game of words, is actually immoral and non-ethical.
