I could care less about the UN. The UN is an attempt to create a world government, and make all countries subject to it.
Sorry, there are lots of countries in the world, and all have different agendas and the UN simply doesn't work like the League of Nations didn't work in the early 20th century.
We were fools for joining after WWII.
I'm sorry, but we live in a dark world ruled by evil, greedy people who lead nations with lots of guns, and bombs, and tanks, and ships, and planes. Each country has it's own agenda determined by the preferences of it's leadership.
The UN attempts to get nations to all agree to similar rules and protocols, but it only works about 10-20 years, then the agendas of the nations diverge and the UN breaks up.
Sorry, but the UN works only as long as everyone wants to play along.
