“Redlines” in war are meant to be objective and unambiguous tests for a country to respond to another nation’s action. If one country uses chemical weapons in a conflict, that might violate the redline of another country and therefore force it to conduct military operations in response to reinforce the international laws and norms against the use of such weapons. Redlines though are often ambiguous, used poorly, and their deterrence effect is often diminished by a lack of credibility. How should leaders — from politicians to entrepreneurs — think about redlines? To answer that, host Danny Crichton was joined by Josh Wolfe and General Tony “T2” Thomas, the 11th Commander of U.S. Special Operations Command (USSOCOM) and venture partner at Lux Capital, to talk all things redlines from a hotel lobby in sunny Miami.
