Difficulties and solutions
"Because of asset shortfalls, we’re unable to get after 74 percent of suspected maritime drug smuggling," Southern Command Cmdr. Marine Gen. John Kelly was quoted as saying in 2014. In 2015 there was a 50% increase in the number of US cutters and an increase in maritime aircraft patrols. (1,426 maritime drug movements were documented in 2014, JIATF-South was only able to target 383).
With 14 nations working together, the co-ordination of operations is essential. Between October 2014 and April 2015 64% of all seizures and disruptions involved a non US nation’s participation, of which most were critical to the success of the seizure. Allied and Partner Nations vessels and aircraft often being used to spot, identify and monitor potential smugglers before passing the information to US intercepts.
The United Nations Office on Drugs and Crime (UNOCD) estimate the 2013 annual world production of cocaine at between 660 and 900 tons. Seizures in Operation Martillo rising from 78 tons in 2012 to 162 tons in 2013. UNOCD indicating in 2015 an increased production in Columbia of 44% and Costa Rica estimating a dramatic rise in world production in 2016.
