There are five statues near the Dutch parliament:
1. William of Orange, seen as the father of the Dutch republic in the 16th century.
2. King William II who fought at Waterloo.
3. Johan van Oldenbarnevelt, who opposed Maurits of Orange in the 17th century and was beheaded because of it.
4. Johan de Witt who was lynched by Orangists.
5. Thorbecke, who argued for a liberal constitution in the 19th century against king William II and III. In 1848 the Netherlands got a liberal constitution and the king lost his power.

So the best best chance of getting a statue in The Hague is opposing a member of the Orange family.
