Sounds to me like the scumbags have issued a declaration of war.
We should treat it as such. Close with and destroy the enemy. In their homes, places of “work”, on the seas, where ever, how ever necessary. End their days. Also, heap punishment and horror upon those who support them, assist them, profit from them.
Kill them. And keep killing them until they have nothing left in themselves but weeping, misery and expectation of violent death.
Leave those who survive with a deep fear and loathing of even the idea of taking up arms against us for generations to come.
That’s the road to peace.
It’s not a declaration of war. It’s a royal temper snit because Mr. Pirate’s life is becoming risky.
