What is the political viewpoint of the United Nations?

Generally, the United Nations desires peace, but is willing to fight for it.

There are large blocs within the UN, such as America and her allies, and the Non-Alligned movement, but there is no general consensus of opinion.

They are probably more consequentialist than deontological in philosophical terms, as they are willing to kill to save lives, being concerned with the consequences of their actions, rather than solely believing that any murder is immoral.
