Tim Sample is an Arlington resident and the CEO and Co-Founder of 72 Africa, a non-profit committed to conflict resolution and promoting peace in Africa.  We asked Tim to join us and talk about some of the sustainable peacemaking lessons he’s learned over a 40 year career working mostly in the intelligence and policy communities, and how those lessons can help us work through the current challenges we’re facing as a nation.  Tim talks about the danger and promise of an increasingly young African population, the threat of influence by violent extremists, and how this threat could affect our country.
