Havana - Cuban President Miguel Diaz-Canel called Monday the response of Cuban singer-songwriter Silvio Rodriguez to Panamanian singer Ruben Blades as forceful.

'Very good for Silvio, forceful in his arguments,' wrote the President in his Twitter @DiazCanelB.

Rodriguez responded to Blades' criticisms, who questioned the Venezuelan government and President Nicolas Maduro because of the situation in the South American country.

True revolutions are always difficult. Che Guevara knew something about that and said that, in true revolutions, you win or you die, because a revolution is not a quiet, peaceful work of charity, like when the fancy ladies of high society go out to do charity to those who have no justice', Rodriguez said in his letter.

'Could it be possible that he doesn't know what a social revolution is', Rodriguez asks in his letter.

A revolution is a turnaround, a rupture, an abrupt change of perspective. It's when the oppressed stop believing that those who rule - those who oppress them - have the truth on their side, and think that the world may be different than it has been until then, Rodriguez said.

But of course', continued the author of Ojala, 'the oppressors do not resign themselves to abandoning their positions of domination and fight to the death and life for them, even though apparently the 'others' are their fellow countrymen: they immediately alienate themselves from the majority of the people, because revolutions - not coups d'état - are always the work of the majority.

'I explain everything to myself, but I have the sadness that I will no longer be able to hear Ruben Blades as the singer of our America that he wanted to be', Silvio Rodriguez said.
