 Further concluding that the Croatian Army was involved in the campaign, the ICTY defined the events as an international conflict between Bosnia and Herzegovina and Croatia.Former Croatian president Stjepan Mesić revealed thousands of documents and audio tapes recorded by Franjo Tuđman about his plans during a case against Croat leaders from Bosnia and Herzegovina for war crimes committed against Bosniaks.During the trial against Tihomir Blaškić, who was the HVO commander for the Central Bosnian Operative Zone, for the crimes in Ahmići, the defence argued that there was a parallel line of command surpassing Blaškić that went to the political leadership of Herzeg-Bosnia.
