By the end of this month the United Nations Peacekeeping Mission in Liberia will no longer exist. The mission, known as UNMIL, is closing shop after nearly 15 years in operation, and its closing this is a major milestone and success for both Liberia and the United Nations. In 2003, it was hard to imagine this day would ever come. Around 250,000 people had been killed in a singularly brutal civil war, the infrastructure that existed in the country was decimated and most Liberians who had the opportunity to leave country had fled. Fifteen years later, thanks in large part to this UN Peacekeeping Force, Liberia is a stable democracy with a rapidly developing economy. In 2006 it was the first country in Africa to elect a female head of State, Ellen Johnson Sirleaf, and after serving two terms she stepped down peacefully and ceded power to her political rival, George Weah. To be sure, Liberia is still a very poor country. But these last 15 years have seen tremendous progress. On the line with me to discuss how UNMIL was able to work itself out of a job is retired Col. Christopher Holshek. Col. Holshek was one of the few Americans to serve in UNMIL and he explains just how the UN's role in Liberia transitioned from peace keeping to peace building.  And because there are so few American military officers who serve in UN peacekeeping missions, his perspective on this question is very unique. The folding of the UN Mission in Liberia is a good news story coming out of the UN and I am glad to share it with you.
