@DavidSalo The simpler explanation is the wind-up Godzilla strategy: put in place an agent that will act autonomously, unpredictably but mostly to your benefit.
You don't have to worry about giving it orders, or risk its getting caught taking orders from you -- because it's clearly autonomous.
At the very least it distracts your enemy, at best it does real damage. Sometimes it backfires, but so do perfectly directed agents.
Trump is Putin's wind-up Godzilla, Cannon is Trump's.
