A multi-billion dollar US anti-drugs programme has failed in its plan to cut cocaine production in Colombia. A US Congressional report says coca cultivation in fact rose by 15 per cent between 2000 and 2006. As a result Colombia remains the world's top cocaine producer and is reportedly the source of 90 per cent of the drug in the US. The report says the aid programme did succeed in reducing Colombia's kidnapping and murder rates. The programme, started in 1999, trained Colombian forces and provided equipment and intelligence to combat drug-traffickers and eliminate coca crops.NO surprise there either. The whole "War on Drugs" has been a colossal failure in terms of its stated objectives, but it has been one of the major pillars of imposing ever more draconian restrictions on liberty and civil rights - just as the war on terror has been.
