In Yemen, the world’s biggest humanitarian crisis you’ve probably never heard of, 80 percent of people need international aid just to survive. Two-thirds are hungry, and half don’t know where their next meal will come from.

Life is very hard in Yemen, UN Resident Coordinator David Gressly tells Ian Bremmer. Most infrastructure is destroyed, few can access clean water or health care, and many Yemenis are afraid to go outside because of landmines.

Meanwhile, 1.2 million civil servants continue to show up to work, with little or no pay. If they stayed home, the state would cease to exist.
