To reduce armed forces and weapons production facilities.
Explanation:
I modify the military reductions portion of the Treaty of Versailles by decreasing the number of German armed forces below 100000 and limited the production of warfare and weapons by taking the production facilities under the control of union countries. These reduction in armed forces and weapons production make the German forces weak and they are unable to attack other countries but can defend themselves so decreasing armed forces and weapons can decrease the power of Germany.
