The idea that it's Volkel seems reasonably solid unless somebody has photographs known to be from somewhere else which look like that. We know Volkel's B61s are stored in a place exactly like that, we know most US airbases don't look exactly like that even in Europe.
So the biggest open question is: Did they prang a real bomb or is that a training unit. I mean, one reason you put so much work into training is that people do prang real bombs and it's important they don't freak out and instead follow procedure. So both are actually likely.
Consider that a state-level adversary would definitely want to plant “fake news” like this (done indirectly through third-parties, of course), for reasons including:
• bogging down our day-to-day operations as everyone “investigates” and “double-checks”
• observing who in our organization reacts and how, revealing personnel, command structures, and capabilities.
• undermine confidence in current leadership
To be clear I’m not saying this particular instance is fake or real, just that this is a technique that can be used to gather information or tie-up on an adversary.
The article in on the website of the Federation of American Scientists. Quote from their About page:
"The Federation of American Scientists is a nonprofit policy research and advocacy organization founded in 1945 to meet national security challenges with evidence-based, scientifically-driven, and nonpartisan policy, analysis, and research."
Hardly the "news media" or clickbait.
