Your editorial on the so-called war on drugs (Donald Trump is turning a failed metaphor into a more dangerous reality, 7 September) is correct: the extrajudicial killing of alleged drug traffickers will not solve the US fentanyl crisis.
Anyone who has followed past attempts to militarise drug law enforcement will know that such efforts are bound to fail. For instance, despite billions in military and counternarcotics assistance by successive US administrations, Colombia now produces more cocaine than ever before, flooding a rapidly growing market.
