PurposeThis paper examines the implications, for States Parties, of the 1954 Convention safeguarding regime in the context of contemporary non-international armed conflict and ANSAs, with a general focus on the Middle East and in situ cultural property.Design/methodology/approachAs the nature of conflict changes and armed forces become further engaged in supporting peacekeeping operations and deliver training to host nation security forces, and human security becomes an increasingly important function of military operations, the protection of cultural heritage (as an expression of a people's identity) becomes a significant contribution to individual operations.FindingsInternational obligations to States Parties for the in situ protection of cultural heritage, under both International Humanitarian Law and HC54, become an ever increasing important responsibility for armed forces to help deliver.Research limitations/implicationsWhile NATO is increasingly focussed on the defence of western states parties from threats posed by the Russian Federation, and observing a commercially and military assertive China, a recent report issued by the Pentagon noted that the Islamic State in Iraq and Syria (ISIS) is regrouping in Iraq faster than in Syria and could regain territory in six to twelve months in the absence of sustained military pressure.Practical implicationsPreservation in situ is used by heritage professionals to refer to the protection of a cultural heritage asset in its original location while the in situ protection of cultural property is a cornerstone topic of the 1954 Hague Convention Special Protection category. The Convention was drafted with international armed conflict in mind but the initial signatories to the Convention had sufficient foresight to consider non-international armed conflict and its potential effect on in situ cultural property by parties to the conflict, including Armed Non-State Actors (ANSA)Social implicationsUN Security Council Resolution 2449 (December 2018) recognized the negative impact of the presence, violent extremist ideology and actions on stability in Syria and the region of both Islamic State of Iraq and the Levant (ISIL) and the Al-Nusrah Front (ANF). This includes not only the devastating humanitarian impact on civilian populations but also the unlawful destruction of cultural heritage.Originality/valueANSAs comprise individuals and groups that are wholly or partly independent of State governments and which threaten or use violence to achieve their goals, such as Islamic State. As such, the military operating environment has changed since 1954.
