UNITED NATIONS — On Jan. 1, the next United Nations secretary-general will take over an aging organization still controlled by World War II powers. What will the world need from that person? Once a major player in solving conflicts and crises around the world, the 81-year-old institution has been sidelined from the top table in trying to end the wars in Iran, Ukraine and Gaza. And its precarious financial situation — caused mainly by the billions of dollars the United States owes — has forced major cuts to its humanitarian and development programs where it has remained a key player. The annual global gathering of world leaders at the United Nations that ended last week shed some light on what the next U.N. chief needs to focus on and pursue. In his farewell address to the General Assembly, outgoing Secretary-General Antonio Guterres told global leaders, “The world does not need a weaker United Nations.” “It needs a U.N. strong enough to face the world as it is," he said, “and determined enough to build the world as it should.” But is that even possible? Much talk of a share
