In front of a plaque, in a modest park in this capital, a group of citizens paid tribute to the Rosenbergs, the day that marks 53 years of their execution in the United States.

They are members or convened by the Cuban Movement for Peace and the Cuban Institute of Friendship with the Peoples, urging not to forget and condemn one of the most shameful acts of injustice of the Cold War.

The couple, Ethel and Julius Rosenberg, were executed in the electric chair at the Sing Sing prison, on June 19, 1953.

They had been detained in the summer of 1950, on charges with espionage and revealing the secret of the atomic bomb to the Union of Soviet Socialist Republics (USSR).

Judge Kaufman, who sentenced them to death, considered that such "acts were more severe than a murder."

Mobilizations of millions of people who demanded clemency in different latitudes of the planet did not matter.

Neither the couple's two children, Michael and Robert, seven and ten years old, were orphaned.

"Save the Rosenberg" became an international slogan in which scientists such as Albert Einstein and Pablo Picasso agreed.

But the Rosenbergs were scapegoats of a change in the world correlation of forces, contrary to downloading the anti-American establishment.
