How do you know? I talked with a Guevara's close aide at the Ministry and he's not so radical nowadays. Don't forget Guevara would be 81 y.o. this June.
Guevara was against Castro's embrace of the soviet model. But today Castro supports center-left democratic regimes in Latin America.
We know that the Kirchners aren't revolutionaries, but against them are all those who want to go back to the agro-business model and seek the IMF financial control. Thanks, but no thanks.

One could answer like Che would do: "It's time for another revolution."
