They didn't do all you said, because if they had done it, they wouldn't have been able to run in May elections. But ETA is intelligent. they're running Bildu with unknown people, ETA supporters, who have never been famous by their political views (excluding Garitano, the "GARA" jornalist, who, yes, was, and is, an etarra).
My english is not good enough to answer all that... but I have friends in the Basque Country, one of them is Arizt Arrieta, who succeded Isaias Carrasco as General Secretary of PSOE in Mondragon after ETA killed him. And I've talked to Patxi Lopez, Odon Elorza among others, and everybody knows ETA is USING the democracy to get money and power.
I have also one good friend who is PeNeuVista, Alvaro Lopez de Verde. A nationalist, no doubts. He lives in Bilbao. And agrees Bild and ETA are the same thing.
You may know a lot about Basque politicians... unfortunately, you have to VISIT it and talk to the people to know if I'm being dishonest
Talking about the PSE-PP pact... well, Patxi would have not done that if Ibarretxe wasn't PNV's candidate. Put Erkoreka there, and you would have a PNV lehendakari and a PSE vicelehendakari. It was necessary to "kill" Ibarretxe politically. PSOE voters wouldn't have understood why Ibarretxe continued there if Patxi could have governed himself.
And Basagoiti had promissed not to enter the Basque Government. In fact, Patxi prefers to pact with the PNV.
Hash, I know you like Spain a lot. You should really visit my beautiful country, and talk to Bildu, PSOE, PP, PNV, CiU.. voters. I think you would understand my views on Bildu. ETA has hurt Spain a lot, lots of people have been killed by them, innocent people... And Garitano appeared the other day on TV with etarra's families, ETA has done SOME WRONG THINGS IN CATALUNYA!!!!!!!!!!!!! What about the wrong things (only some) in the rest of Spain?
