  The tribunal often faced, and to some extent still faces, accusations of inefficacy. Ad hoc tribunals lack their own coercive power and rely on the support of individual nation-states. Little progress was initially made in the 1990s towards the capture of important war criminals in the former Yugoslavia. Yugoslavia was not then in a truly transitional state such as found in Germany or Japan at the end of WWII, as the Serbian government of Slobodan Milošević, who had supported the Bosnian Serb commanders, remained in power. There was, as in other regions in which war crimes have occurred, hostility to outside monitoring and extranational justice. This was also seen to a lesser extent in Croatia. However, national (or domestic) justice proved itself to be overwhelmingly corrupt, biased, incompetent, and inadequate.
