Securing Tomorrow @ The Washington Post | March 30

The next commander in chief will face complex challenges in a world marked by wars and cyber crimes, polarized by ideological beliefs and divided by seismic shifts in geopolitics.

The U.S. is struggling to contain a growing Islamic State, and Syria’s humanitarian crisis and civil war has deepened and become more complicated. Seas are rising and communities imperiled by climate change face severe erosion. Disease and natural disaster have devastated parts of the world laden with shortages and aggravated by drought, famine and lack of infrastructure. China’s economy is contracting, rogue players have access to the Internet and how the U.S. keeps pace in a rapidly changing world will take epoch-making consideration.

In a year voters are anxious and angry, Washington Post columnist David Ignatius will interview newsmakers in defense, intelligence and national security in live onstage conversations to better understand what’s at stake for the world in 2016 and beyond.

Ignatius’s first conversation was on March 30 with Robert Work, the deputy secretary of defense, who has been a a leading voice for the Pentagon in cyber defense and innovation. Watch the full conversation above and highlights below.
