FWIW, that doesn't really even make sense. If you had direct knowledge only of the
planning, then what's the source for the execution? I don't think anyone would be surprised that there was a plan for doing this. The US plans lots of stuff. Why did "planning" even appear in that sentence? Why not "a source with direct knowledge of the operation"?
Again, there's a huge weasel word right there in the only sourcing for the whole article. That just... yikes. Maybe it's a typo. Maybe it's something an editor could have cleaned up. But maybe it's also the sort of thing Hersh's editors simply threw out as unpublishable, which is why it's an uneditted substack blog.
