You know that do you you? Once again you assume more than you know.
I rang someone 2 hours after at about 9.45 GMT (who was in a conference discussing it). Surprisingly, they took my call, and was told very quickly "I don't work in New York anymore, and I don't drink in Finnegans Wake". As this was the venue where conversations of a previous nature had occurred between me and them, it pretty clearly told me who was responsible (the exchange lasted about 20 secs, as other priorities dominated that morning). Where as the government concerned would have a better intelligence network than the Spanish, it's inconcievable that Aznar didn't know. Your own common sense should have told you it wasn't an ETA attack in any case (not really their modus operandi)
Unfortunately Suny it is you who has demonstrated time and time again a complete inability to read world affairs, with your continual and monumental tactical misjudgements (Iraq being the most obvious). You migth care to track down America's own record at releasing radioatcive material in Spain? Or perhaps you don't know about it?
I'll give you a clue, it involves a B52 colliding with a refuelling plane in 1966. But then again, you were under a fascist Dictatorship so won't have been told. Mind you it explains why you're still struggling with Zapatero being democratically elected rather than a coup as you allege. I suppose we need to remember that the concept is still quite new to you, and so a period of adjustment is probably necessary whilst you reconcile the two
