In an op-ed published in The Washington Post on January 4, Neil Howe and Richard Jackson of the Center for Strategic and International Studies (CSIS) sound the alarm about the "massive disruption" the world may face in the 2020s due to population aging. Howe and Jackson co-authored The Graying of the Great Powers (see New Security Beat review), a 2008 CSIS report that elaborates on the supposed "political warfare" that will break out as a result of aging in the developed world, accompanied by turmoil in developing countries with young populations.
