Judges at the International Criminal Court have approved a formal investigation into President Rodrigo Duterte’s drug war, a bloody campaign that has killed thousands of people. The investigation will also cover similar killings in Judges at the International Criminal Courtfrom November 2011 until Duterte was elected president in 2016.  Duterte’s spokesman played down this important development at the ICC insisting it won’t move since his administration would not cooperate. But can a government’s refusal to cooperate in fact stall an ICC investigation? Or will it only bring more harm than good for the likes of Duterte?
