Although warfare has changed dramatically since the Geneva Conventions of 1949, they are still considered the cornerstone of contemporary international humanitarian law. They protect combatants who find themselves "hors de combat," and they protect civilians caught up in the zone of war. These treaties came into play for all recent international armed conflicts, including the War in Afghanistan, the 2003 invasion of Iraq, the invasion of Chechnya (1994–present), and the Russo-Georgian War. The Geneva Conventions also protect those affected by non-international armed conflicts such as the Syrian Civil War.
