Colonel Randall Larsen is a retired US Air Force Colonel and is the national security advisor at the Johns Hopkins Center for Health Security and a senior fellow at the Homeland Security Policy Institute at George Washington University. He formerly served as a professor and department chair at the National War College, the founding director of the Institute for Homeland Security, the executive director of the bipartisan Congressional Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism. The world seems a fragile place in 2017, political tensions are aired on the news, and twitter, everyday. There is no longer a balance of Superpowers, and attacks from small groups or individuals have become more frequent. So what if one of these attacks was carried out, but instead of guns or explosives, the weapon of choice was a biological weapon designed to infect as many people as possible? Is it a real threat or is it just a conspiracy - has anyone tried to do it before or will nature throw something at us before anyone can weaponise a disease? These are just some of the things Randy was able to tell us about. WTSpod is brought to you by Fitzpatrck Castle Hotel, go to www.fitzpatrickcastle.com for more.
