The veto power has been criticized for its undemocratic nature. A single country can prevent a majority of the Security Council from taking any action. For example, the United States routinely casts lone vetoes of resolutions criticizing Israel. The permanent members also veto resolutions that criticize their own actions. In 2014, Russia vetoed a resolution condemning its annexation of Crimea. Amnesty International claimed that the five permanent members had used their veto to "promote their political self interest or geopolitical interest above the interest of protecting civilians."
