The real purpose of state secrecy is to enable governments to establish their own self-interested and often mendacious version of the truth by the careful selection of "facts” to be passed on to the public. They feel enraged by any revelation of what they really know, or by any alternative source of information. Such threats to their control of the news agenda must be suppressed where possible and, where not, those responsible must be pursued and punished.
Revealing important information about the Yemen war – in which at least 70,000 people have been killed – is the reason why the US government is persecuting both Assange and Zikry.
