Pirates had hideouts and treasure maps, because they needed to protect their families and those they rescued. They also needed places to store and then redistribute gold, goods and weapons. It was like an underground railroad movement, but global. They were a more militaristic Robin Hood collective. They strategized and had a military manual.
The spirit of pirates still lives on in those who live off-grid and in vans/RVs, preppers, Anonymous, WikiLeaks, Truthers, conspiracy researchers, and counter-infiltrators.
Pirates did need to send spies and infiltrators to recruit more military men and discover how the satanic cabal was going to respond to their moves. The pirates were disrupting their money flow and power.

Don't they sound like the Earth Alliance? The only difference is that the military dissidents decided to take over the military instead of leaving it... And then they put their own Commander In Chief.

Trust the plan.
