The United Nations turned 65 last week. In human history, this has been the fourth attempt at a layer of global governance, and it is the longest-lasting, with U.N. membership growing from 50 countries in 1947 to 192 today. Though 50 years of fighting between the Soviet Union and the United States kept much of the U.N.'s activism at a stalemate, that is now over, and the world has grown closer in the age of satellites, the Internet and air transportation. It is time to give the U.N. the strength to abolish nuclear weapons, to replace war with world law, and to work in unity to address the world's pollution and water problems, human trafficking, disease and world economic problems. We all saw how wonderfully the human family worked in concert during the Chile mining rescue. It is time to use our combined powers to make this world work for all. I am proud that my forbearers had the foresight to develop the U.N. I will be prouder if my own generation finally moves the U.N. toward the important tasks it was ultimately designed for.
