1 The UN Security Council was created in 1945. It is made up of 10 rotating (轮值的) members and five permanent members, which have a veto, the power to stop a resolution (决议). Most UN members now consider the organization"s structure outdated． But any changes need the agreement of two-thirds of the 191 members, and no veto from any of the five permanent council members. Last year, Japan, Germany, Brazil and India formed a lobbying (游说) group to get permanent council seats.
