One of the effects of the globalization of our information environment is that diplomacy, even in places like China, is no longer the sole province of envoys meeting furtively behind closed doors. International relations has gone, in part, open source, hence the rise of fields like public diplomacy and strategic communication.

The media revolution has changed the way governments talk to the citizens of other countries, and this pdf book examines the crisis into which this disruption has thrown strategic communications establishments worldwide.
Fascinating stuff: the line between propaganda, psychological operations, and Twitter falls, but the bar for effective strategic communications rises in an environment where every statement is under the public microscope.
