A third type of criticism centers on the event-based and inconsistent nature of most policies on humanitarian intervention. These critics argue that there is a tendency for the concept to be invoked in the heat of action, giving the appearance of propriety for Western television viewers, but that it neglects the conflicts that are forgotten by the media or occur based on chronic distresses rather than sudden crises. Henry Kissinger, for example, finds that Bill Clinton's practice of humanitarian intervention was wildly inconsistent. The US launched two military campaigns against Serbia while ignoring more widespread slaughter in Rwanda, justifying the Russian assault on Chechnya, and welcoming to the United States the second-ranking military official of a widely recognized severe human rights violator - the communist government of North Korea.
