The Biden approach: A US drone strike in Kabul on August 29 killed 10 civilians, including an aid worker and seven children. It was not an isolated incident. Drone strikes conducted by the US, in Afghanistan and beyond, have often resulted in civilian casualties. The Trump approach: Qasem Soleimani, who was killed by a US airstrike ordered by President Donald Trump at Baghdad International Airport on Friday, was hailed as a hero in Iran -- brave, charismatic and beloved by the troops.
