In order to solve the Libya crisis, the UN Security Council adopted, by applying the principle of "responsibility to protect" for the first time, a Resolution on the Libya issue, based on which the France—UK-US alliance conducted air assaults on Libya. Tremendous consequences will be thus produced on the future moves of international law and international relationships, in that many of the traditional principles in international law have been put under challenge and that international law itself is at a stage of being transformed. Resulted from the European countries' practice in response to the Libya crisis, possible changes in international law may take place in the following four aspects, namely, settlement of international disputes with a peaceful means or by use of force, the "responsibility to protect" and rationale for using force, use of force and the principle of non-intervention in the internal affairs of the other states, and the underlying principles for the recognition of a government in international law.
