Or to simplify my point....

When you get into specifics it stops sounding like the assassination of Franz Ferdinand was a jewish conspiracy to serve jewish interests, and starts sounding more like it was a conspiracy for Serbian nationalism and communist interests, done by a jew.

Seems like the concept of a jewish conspiracy evaporates when generalities are no longer used, and events are described in specific terms.

Or at the very least it's laid bare that a "jewish conspiracy" is broadly defined as any conspiracy involving any jew.
