I'm not sure why this question keeps coming up. As stated, the United Nations has no real authority to attack, invade, dismantle, or in other ways maim any country on the face of the planet. They have multiple cases of human rights/civil liberties abuses in North Korea, Iran, Somalia, and now Russia. The U.N. has not been able to do anything. Russia has taped torture of young gay men on the internet... the U.N. has done nothing. Even when a country goes off on its own (think Iraq, or the United States going to war with Iraq), the U.N. has limited power about what it can do and prevent.
Their own Human Rights Act prevents religious intolerance and works for peace between faiths, cultures, and languages. The U. N. are humanitarian blue helmets with automatic weapons filled with vaccinations and strongly worded letters, nothing more.
So what, in all this, says that they have the want, desire, or even the ability to go against an expansive, world-wide immeasurable generalized philosophy concept like “religion?”
