Much like tenured loser Michael Stone in Northern Ireland, at least some component of ETA appears to have walked away from the permanent ceasefire the group declared last March.
In the process, they appear to have killed two Ecuadorean men, despite calls ahead of time to clear the structure. Of course, that might just be one of those risks one takes when destroying huge public buildings. And had they been lucky and not killed anyone over a political issue that lacks support even in their own ethnic base, they'd still be burning through recovery and rebuilding funds that could instead have gone to public health and other services for their people, to the tune of millions upon millions of dollars.
Renouncing violence brought ETA to the bargaining table, against the wishes of the conservative opposition in Spain. Now they've given up on that table in favor of the vanity project of expressing their personal power through indirect violence.
A century of Ian Paisley and Gerry Adams pettiness is better than a day of Michael-Stone-style madness. Whoever's acting out their insecurities in ETA needs to get that message.
