Despite my downward vote for the "The Plantations in West Curaçao" tentative site, this reflects more my support for a transnational nomination rather than several dozen individual nominations. I visited the Savonet and Knip plantations (the later is closed indefinitely) in December 2022. I did a self-guided tour of Savonet. White columns with a fist grasping a broken chain of bondage are located in several locations in West Curaçao and commemorate events preceding, during, and after the 1795 Slave Revolt.
It just so happened that the day before my visit, the Prime Minister of the Netherlands apologized for the Dutch government's role in the Atlantic Slave Trade, calling it a "crime against humanity". While there was some controversy over the apology, it does seem the straightforward language was appreciated by some as a first step. Western governments tend to tread cautiously on sensitive topics related to genocide, slavery, and other crimes against humanity, regretfully because the "r" word is greatly feared and in some countries political suicide. The House of Representatives (in the U.S.) officially apologized to Black Americans for Slavery and Jim Crow Segregation only 15 years ago and reparations remain contested and far from our current reality. So in regards to Netherlands, this may be a long process and actions tend to mean more than words.
I think any extensive transnational "Slavery" nomination would require several sites located in the Caribbean. The components in West Curaçao are well-suited for this type of nomination. One very small step that is not exactly the "r" word, but perhaps might be controversial in some countries. I think a transnational Slavery nomination should be 100% funded by the EU and the United States. Additionally, a collection of funds should be established by Western governments to sustain such properties for the long-term (finances to pay staff, ensure satisfactory maintenance, preservation work, and upkeep/construction of tourist facilities).
