Swiss TV journalist Richard Labeviere details in his book Dollars for Terror how some European super-rightists, especially neo-Nazis, have joined the Islamofascist cause, and even converted to Islam. Surprises me, though, that a Basque nationalist should so convert. Aren't the Basques super-Catholic? I'm Irish (Irish-American, actually, but I have plenty of relatives in Ireland,) and, weakened as the church now is in Ireland, I am sure that any Irish nationalist who actually converted to Islam would immediately forfeit all support in the country. Are the Basques any different?
No. The Basque nationalists are anti-Castillian (anti-Madrid).
The traditional Spanish central government has always been pro-Church. The Basque terrorists could care less about the Catholic Church.
