Shub attended Townsend Harris High School and then joined the Navy in 1945. He graduated from the City College of New York and attended the Medill School of Journalism at Northwestern University and the Graduate School of Journalism at Columbia University.
His first jobs in journalism included writing, and then editing at The New Leader, a leftist but anti-communist magazine whose editor was his brother-in-law, Melvin J. Lasky, and associate editor at Commentary. Next, he was an editor at the New York Times where he won a fellowship from the Institute of Current World Affairs that allowed him to travel in Russia and Eastern Europe.
In 1964, he was hired by the Washington Post to open a bureau in Bonn and report on Germany and Eastern Europe. Next, he was moved to the Moscow bureau where his reporting on dissidents and the political role of the army got him expelled in 1969.
Shub was married to Joyce Lasky (whom he later divorced) and had a son and daughter. He then married (and divorced) the author Barbara (née Bellman) Raskin, the former wife of progressive social critic Marcus Raskin.
