So the police attempt to carry out the order, the Dutch parliament fights back by using the military to seize control. Recognizing the emergency nature of the situation they quickly pass a new law empowering a small "council for citizens safety" to make quick decisions. The council declares martial law and throws all of the Judges and activists in prison as "enemies of the state". With power consolidated and internal dissent quelled they surprise the world by launching an invasion of Belgium beginning with a night attack on Antwerp by elements of the 11th Airmobile Brigade swiftly followed up 13th Motorized and 43rd Mechanized in a lightning pincer maneuver on Brussels. Cut off and surrounded without access to their heavy weapons the Belgian forces quickly surrender. Emboldened by this move right wing forces rally to the Dutch cause and European countries fall like dominoes as the new Dutch empire rises out of the ashes.
Glad to finally have a like minded neighbor Russia offers an alliance which ends up incorporating the Chinese as well as they can see which way the wind is blowing. In a panic over the growing might of the tripartite pact the US launches a nuclear first strike hoping to catch the opposing forces unprepared. US missiles prove far more accurate than anyone expected and flatten the majority of their targets but even the limited retaliatory strike leaves Washington D.C., New York & L.A. as smoking craters and over a hundred million dead stateside.
Governments collapse worldwide as supply chains are stretched beyond their limits. The trucks stop rolling and grocery stores empty. As the food runs out civil order breaks down into mass violence. Over the next six months ninety percent of humanity starves to death and the rest are left to fight wars over cans of dog food in the blasted wastelands. All the dust kicked up by the nuclear exchange creates a cooling effect that cancels out global warming and the lack of working industry means CO2 emissions are way down, so it looks like the activists get their way after all even if none of them are still alive to see it.
