During the Khmer Rouge regime's genocidal wave of terror in Cambodia at least 1.8 million people - about a quarter of the population - died through torture, execution, disease, overwork or starvation. It is a legacy that left millions of Cambodians with psychological scars that the country is ill-equipped to deal with due to deep-rooted mistrust and a lack of money for reconciliation and mental health treatment. I visited a reconciliation project in a village in Cambodia where villagers lived cheek to jowl with the alleged killers of their loved ones.
