What did Alger Hiss' actions lead to?

"For three years, Alger Hiss was the protagonist in a great human drama that made headlines across America. The case polarized the country between 1948 and 1950, becoming a symbol of American policies in the onset of the Cold War. It accelerated the rise of Richard M. Nixon. The debate about Hiss' guilt remains endless, for either he was a traitor or he was the victim of a framing for political advantage at the highest levels of justice."
