I have a wonderful opportunity to speak at the UN, if you had the opportunity to speak at the UN what would you say?

Really a great question to ponder. We all pretty much know that the UN is next to useless and that every single decision is debated to death and then debated again.
I think I would have to respectfully ask them to review their charter and think about what they are really trying to accomplish, because in my opinion, I think that the UN is not doing what they were designed to do. Many countries pay into the UN for relief support and provide troops, but from what I have seen over the years the UN is a toothless old lion. I would urge them to either step up or to close shop.

I would tell them how useless I think they are.

Are you looking for actual suggestions?
