Duterte demands a debate with United Nations officials.
The UN ignores him. Rightly so.
Professionals from humanitarian and investigative world organizations do not waste their precious time arguing with fanatic fools, murderous thugs and hallucinating monarchs.
Instead, they investigate and prosecute them.
Let the tyrants defend themselves before the proper international criminal tribunals.
Do not worry, Duterte. Your own time of reckoning will soon come.
