Although Ingrao initially published on the early modern history of the Habsburg monarchy and the Holy Roman Empire , he refocused his scholarship to ethnic coexistence and conflict during the Yugoslav Wars in the 1990s . Shortly after the Srebrenica massacre , he made the first of over fifty trips to the Balkan war zones to heighten public awareness of the contrast between region ’s history of ethnic coexistence and the humanitarian catastrophe wrought by ethnic nationalism . In 1996 , he uncovered evidence of the Clinton administration ’s duplicity in shielding war criminals from arrest that was reported by NPR and the New York Times . This brought him into the public debate and intra-governmental struggle over US policy . By the late 1990s , he was a regular interview subject for print , radio and television news stories in Europe and North America , as well as a recurring guest on PBS ’s NewsHour with Jim Lehrer . His focus on the interplay of history and contemporary policymaking led to a series of nationally and internationally-syndicated columns and guest lectures across North America , Europe and China before academic , governmental and military audiences , including the US State Department , several US Embassies abroad , the US Capitol , the British House of Commons , S.H.A.P.E. headquarters , and the National Defense University
