"The financiers put up millions for the mother ships and the weapons."

No they do not, the "mother ships" used (usually fishing vessels) have themselves been hijacked or "pirated" they cost the pirates nothing. The last two "mother ships" captured (one by the South Koreans and the second by the Indian Navy) still had their original fishing crews held onboard as hostages.

Fishing vessels are ideal for use as "mother ships" because they do not transit the areas they "loiter" in it. There are also hundreds of them and it is very easy for the pirates to hide in a "fishing fleet", your faith in satellite surveillance is rather naive.

As in the 17th & 18th centuries there is only one way to eradicate the menace of pirates, you destroy the bases from which they operate.

Your "financiers"? A thirty-odd year old Somali widow contibuted her inheritance from her late husband (an AK-47 with three magazines) worth $60. Her return on her investment was reportedly $131,000. Now you tell me if that is an attractive proposition?

Destroy their bases, smash their boats and make them think twice about even walking along a beach let alone attempt to put to sea from one.
