The United Nations: Does it Solve anything?

We had a Model U.N. meeting in history cl this year, it was alot of fun, and it gave an insight into how the U.N. runs things. I was the fake rep for Brazil and i came up with a resolution along with Mexico, Chile, and South Africa. Pakistan voted no, Russia and the US abstained, and the rest voted yes...until China casted its vote-no. One vote, and the entire resolution, which everybody liked, was destroyed. From this experience, my opinion is that the U.N. does not accomplish much because of the veto power the US, Russia, France, China, and the UK have. What are your opinions?
