Every single country in the UN is signed up to the same laws of war, but Israel’s military campaign in Gaza is reminding us interpretations of those laws often differ.

In this extra Sitrep podcast Kate Gerbeau talks to Rev. Nicholas Mercer, who was the British Army’s top legal adviser in Iraq 20 years ago.

He explains the key principles that govern the legality of military action, how he applied them in the midst of battle, and how the Israel Gaza war mirrors many of the difficult decisions he faced in Basra.
