Of Soldiers and Spies by Cy Williams

This fact-based Cold War thriller pits Yuri Andropov and the KGB against President Lyndon Johnson in a fast-action tale through Bolivian mountains, Vietnamese jungles, and Washington's dark alleys. Colonel Bill Dubrowski of the Defense Intelligence Agency attempts to unravel a devious Russian plot to deceive Johnson. The murder of Che Guevara, political assassinations, and deadly moves by a hidden KGB mole are some of the events that culminate in the ignominious defeat of Johnson in 1968.
