Leaving 50,000 people – including the elderly, the vulnerable and the sick – without electricity in Berlin in the middle of winter during the festive season is being passed off as activism?

Why do you think these volunteers supported the attack? I don't think there's a published statement to the effect. Even the U.S. government does not claim that (at least not in its written communication).
