Under one person, one vote, each country's number of votes is directly proportional to its population. This would be similar to how U.S. states are represented in the United States House of Representatives. In "The Future of Sovereignty – Rethinking a Key Concept of International Relations", Hasenclever et al. sum up the advantages and disadvantages of this system: "In a strict meaning of democracy based on individuals as subjects, every person's vote would have to have exactly the same weight. None of the known proposals, however, supports such a strict interpretation, because the inequality among the states' voting powers would be extreme with only four countries – China, India, the United States and the former USSR – disposing of an absolute majority."
