I agree.(to Johan's post about the Schlieffen plan). It does seem a little odd that an AI-Germany never bothers to declare war on Belgium
As an event description, can I suggest something on these lines?
'The Schlieffen Plan'
Trigger: Germany is at war with Russia.
"Ever since France and Russia became allies, Germany had been faced with the possibility of war on two fronts. In 1905, Chief of the General Staff Schlieffen devised the plan that bore his name. It called for a sudden, massive attack in the West, passing through the neutral Low Countries in order to encircle the French Army. The idea was to defeat the French before Russia could mobilise its vast but ponderous forces. However, when the long-feared war actually arrived, Kaiser Wilhelm had an attack of last-minute nerves. He asked his generals to stand on the defensive in the West, cancel the attack on Belgium in case it provoked Britain, and send all their troops against Russia instead. The High Command refused, saying that to change the plan at such short notice would be disastrous."
Choice a: "Stick to the timetable". Declare war on Belgium.
Choice b: "Implement the original Schlieffen plan in full". Declare war on Belgium
and the Netherlands.
Choice c: "Defend in the West, attack in the East" Dissent 10.
If desired, instead of "declare war" trigger the appropriate event for "Germany demands access"
The dissent hit represents disorganised troops without their proper supplies or transport.
