Query: An Indispensable Book for These Times

I couldn't put down "Sorrows of Empire," by Chalmers Johnson. It is a contemporary history lesson made meaningful because it finally focuses the backstory on how this once-great country lost its way in endless wars and interventions. It's a spy thriller and reveals facts about our secret actions and interventions on a global scale that will leave you dumbfounded and quivering. It's required reading for every patriotic citizen, politician, leader and regulator who seek to lead the last superpower back to a prosperous, secure global role.
