How to deal with Pirates

I used to call piracy "4th Generation War upon the seas", but one milblogger had actually likened piracy to "5th Generation Warfare". Piracy has no ideology, and isn't attempting to overthrow government. All it seeks is money.

Which makes it relatively simple to defeat. Sure, we can talk about eliminating the root causes of piracy, and it's certainly a noble goal, but what really reduces piracy is making it completely unprofitable. Thus speaks Sic Semper Tyrannis.

I mean, did we stop robbing banks in large numbers because we eliminated poverty or because we made banks so difficult to rob?
