The Bundeswehr (German Armed Forces) has been using unarmed reconnaissance drones for decades and has recently called for approval for armed combat drones. However, this request has been blocked by the Center-left Social Democrats (SPD) – part of Germany's coalition government – in the German Parliament (The Bundestag). The Bundeswehr was expecting rapid approval from the Bundestag to arm the five Heron TP drones recently acquired from the Israeli manufacturer Israel Aerospace Industries (IAI). However, these drones will operate unarmed, as the vote for “armed drones” has been postponed indefinitely. SPD leader Norbert Walter-Borjans has argued that "the line between defending the lives and limbs of our soldiers and killing with a joystick is very thin" and that such a debate should deserve more time and serious discussion. Two questions arise from this situation: firstly, have other states banned armed drones? And secondly, would the decision to arm drones lead to an increase in conflicts or civilian deaths?
