Reply #5: Not according to the UN Charter. [View All]

The United Nations Charter says in Article 1:

The Purposes of the United Nations are:

1. To maintain international peace and security, and to that end: to take effective collective measures for the prevention and removal of threats to the peace, and for the suppression of acts of aggression or other breaches of the peace, and to bring about by peaceful means, and in conformity with the principles of justice and international law, adjustment or settlement of international disputes or situations which might lead to a breach of the peace;
2. To develop friendly relations among nations based on respect for the principle of equal rights and self-determination of peoples, and to take other appropriate measures to strengthen universal peace;

The interdiction of aggressive war was confirmed and broadened by the United Nations' Charter, which states in article 2, paragraph 4 that

All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations.

c - The "sovereignty" rule means that it is a crime of aggression to use armed force with intent to overthrow the government of a state or to impede its freedom to act unhindered, as it sees fit, throughout its jurisdiction.
