Assembly of the United Nations is an advisory
body which represents each member nation, and gives each member nation
one vote regardless of the size, population, and power of the member.
It does not represent people, and its power will not likely be more than advisory so long as it gives equal votes to small and large members alike.
It has had some value as a means of expressing the viewpoints of individual member-states, or blocs of members which share certain common interests. It has, on occasion served a useful goal, particularly when the Security council was paralyzed, to support the actions of the Seceretary-General of the UN, or to confirm a strong consensus in favor of a certain action.
