Like Aruba Curacao has achieved a semi-independence from the Netherlands, local autonomy but existing under the defense/foreign affairs umbrella of the Netherlands. This status is not unlike that of the U.S. commonwealths like Puerto Rico, where we go later on this cruise.
These islands, often called the A-B-C islands (for Aruba, Bonaire, Curacao), sit very close to Venezuela, Hugo Chavez's home. Most of their produce comes from Venezuela.
I suspect the ABCs need the Netherlands to keep Chavez from sweeping them into his orbit, for I'm sure Venezuela has a long-standing claim to these three offshore islands, like Argentina's claim to the Falklands (aka, las Malvinas).
