There must always be a place for necessary whistleblowing from inside governments. This newspaper will always stand, responsibly, for that principle. Yet leaks are also serious matters, which challenge a state. In a particularly serious case, or at a particularly serious time, such as during a war, a leak can help an enemy, dismay allies, weaken morale and, at least potentially, change the military balance and put lives at risk.
The leak of highly classified US intelligence documents covering plans to aid Ukraine’s war against Russia is unquestionably grave, both in its content and context. In Ukraine, Nato is in the midst of by far its most serious conflict for a generation. The inherent seriousness of the leaks is enhanced by other factors, including the details and numbers they contained, the breadth of the secrets’ online distribution, including to potential enemies, the length of time they were accessible, and the likelihood that the material becomes part of a disinformation campaign.
