If we are successful in making a contribution that advances the aims of the United Nations, if we are able to join in making a contribution to the building of a better world, then membership in the United Nations will have been worth it for us, too.
如果我们成功地作出促进联合国目标的贡献，如果我们能够参加促进建立一个更美好的世界，那么加入联合国对我们来说也是值得的。
