Based on this excerpt, what was the member nations' stance on war and use of armed force?War declared on one member nation has no bearing on the other members. War is justified if the group's shared goals are being threatened. War for any purpose is unnecessary and inhumane. War places too much of a financial burden on nations and should be avoided.

B. War is justified if the group's shared goals are being threatened

Explanation:

The statement in the preamble given by the UN is that armed forces shall not be used, save in the common interest of the member nations. In this sentence, save is used as a conjunction to mean except. So, the resolution of the UN from this statement is that war and its disastrous consequences must be avoided at all costs, but that if the shared interests or goals of the member nations are being threatened, then that is the only condition in which war can be fought.

This preamble was established by the members nations gathered in San Francisco during the establishment of the UN as an organization.
