"Blacklisting" the Netherlands from receiving any oil or oil products? A member state of the European Union with Borders to Germany and Belgium and with access to the North Sea? Who should do this "blacklisting", Royal Dutch Shell, headquartered in The Hague, NL? And who is supposed to enforce it? Even if there was a case for such a thing, which there isn't, no member state of the EU ever would dream of doing any such thing, since that would violate the Four Freedoms doctrine of the EU, and also because the neighbors get a sizable part of their oil and oil products through Rotterdam.
