Batasuna for Dialogue, Stirs Basque
Madrid, Jan 11 (Prensa Latina) The announced participation of the illegal political organization Batasuna in the march against the ETA attack at the Barajas Airport, scheduled for Saturday in Bilbao, has caused a huge commotion among Basque political parties, it was revealed on Thursday.
Basque government spokeswoman Miren Azkarate asked pro-independence politicians to clarify whether they will be calling for the end of ETA during the protest, convened by regional President Juan Jose Ibarretxe.
Accompanied by his colleagues Joseba Permach, Joana Regueiro, and Imanol Iparragirre, he affirmed they will attend the march with the slogan "For Peace and Dialogue."
Batasuna leader Pernando Barrena told press in San Sebastian they will join the march because "it is the right time to give an impulse to the political process" in the Basque country.
And why not?
Besides ETA, the only ones that have been working towards the strenghtening of dialogue as a solution to the Basque issue are the people from Batasuna. Everyone else was taking profits and politics above peace and the right of a people to their self determination. Plus, the decision to go to the demonstration situates Ibarretxe and the pseudo-socialists from the PSOE on the spot light.
