A particularly relevant scenario in which I would need a good understanding of IHL in order to responsibly perform my professional tasks would be the following: a participation as an international observer to the OSCE Special Monitoring Mission in Ukraine. As the main objectives of this mission are to monitor the withdrawal of heavy weapons, to ensure the full implementation of the Minsk documents and of the agreed ceasefire between the parties, as well as to facilitate the delivery of humanitarian assistance, a sound knowledge of IHL would be instrumental to engage in fruitful interaction with the State’s armed forces and the Non-State armed groups. A good understanding of IHL would therefore contribute to the success of the OSCE mission on the ground and enhance its legitimacy, both locally and internationally.
