However, many economists and politicians maintain that the power of supranational organizations such as the WTO is limited to what nation-states collectively agree to giant. They argue that bodies such as the United Nations and the WTO exist to serve the collective interests of member states, not to subvert those interests. Supporters of supranational organizations point out that the power of these bodies rests largely on their ability to persuade member states to follow a certain action. If these bodies fail to serve the collective interests of member states, those states will withdraw their support and the individual nation-states, not supranational organizations.
