Why navies police some pirate regions more heavily

Why do navies concentrate anti-piracy forces in some regions rather than others?

Navies oppose piracy in principle, but politicians fund sustained action where commercial traffic makes the threat economically important.

Navies generally dislike piracy because it challenges their monopoly on organized violence at sea. Operational attention still follows political choice: governments are more likely to fund patrols where enough trade is exposed to make disruption costly. This separates a navy's institutional preference from the budget decision that determines where ships actually deploy. It also explains why heavily trafficked routes recur as major anti-piracy theaters.
