Paul Wolfowitz and Michael O'Hanlon explore the Colombia model and how it might apply to Afghanistan:
Strange though it may sound, success in Afghanistan would look a lot more like the success that has been achieved in Colombia over the last 10 years, rather than the success that we are hoping for in Iraq. This is a point that was made two-and-a-half years ago by Scott Wilson, a Washington Post reporter who had spent four years in Colombia as a correspondent and a year in Iraq. Writing in April 2009, Wilson said that Obama "may want to look south rather than east in charting a new course" for Afghanistan. Though they hide in triple-canopy jungles rather than forbidding mountains, the insurgents in Colombia, like those in Afghanistan, will always enjoy the benefit of sanctuaries inside the country. And, until Pakistan withdraws its support for the Taliban, Pakistan will cause the same problems for the Afghan government that Venezuela does for Colombia.
Whole thing here.
