Bob Keeler is a retired journalist and an unretired peace activist. During his decades at Newsday, he was Suffolk County reporter, Albany bureau chief, Sunday magazine editor, and a member of the editorial board. He won a Pulitzer prize for a series about a Catholic parish in Westbury, Long Island. His father and brother were soldiers, and he is an army veteran. But he belongs to the Catholic peace group Pax Christi and is planning a book about America’s dangerous worship of the military, an institution he considers unworthy of worship.
