Heyberger also wrote two books responding to the major challenges that have faced Middle Eastern Christian communities in the post-9/11 era, especially in light of social upheavals caused by the U.S. invasion of Iraq in 2003, and, from 2011, the Syrian Civil War.  These books are "Les Chrétiens au Proche-Orient: De la compassion à la compréhension" (2013); and "Les Chrétiens d’Orient" (2017).  The latter considers the long and ambiguous impact of European – and especially French, British, and Russian – intervention in the region relative to Middle Eastern Christian communities.  This book takes the story of Middle Eastern Christians into the early twenty-first century while commenting on the Islamist militant movement known as ISIS or Da’esh.
