Another question about his proposal would be: does he think young adults should offer themselves to serve as "civilians" (if they don't want to join the military) in dangerous areas of the world, whether because of terrorism, radical Islam, drug gangs, kidnappings, and the like, or disease (Ebola), and then face the life of a "victim" when returning if they come back. That's my immediate reaction now. I wonder about this as churches often send youth group on summer missions in Central America where teens and college students learn to mix with people in more earthy cultures.
