Gibraltar isn’t illegally occupied, that said Spain has always been stuck between a rock and a hard place since they have their own walled off enclaves in Morocco and they also have problems with independence movements internally with both Catalonia and the Basques claiming independence to various degree. This is why regardless of how much Spain wants to push the UK to secede Gibraltar they can’t push too hard. The Netherlands have the same problem they also have remote territories under their control so again they can only abstain.
