Washington. US military analyst Daniel Ellsberg, whose change of heart on the Vietnam War prompted him to leak the classified “Pentagon Papers,” exposed US government deception about the war and set off a major freedom-of-the-press war, Friday passed away at the age of 92, his family said in a statement. Ellsberg, who was diagnosed with inoperable pancreatic cancer in February, died at his home in Kensington, California, the family said.
