This won’t end well.
To have an effective military you will need to install an enormous amount of pride in your country, which results in nationalism. And you will have an enemy to create propaganda.
I have seen this story before.
why didn’t your story play out when the Bundeswehr was at this stage?
“the Bundeswehr had 12 Army divisions with 36 brigades and far more than 7,000 battle tanks, armoured infantry fighting vehicles and other tanks; 15 flying combat units in the Air Force and the Navy with some 1,000 combat aircraft; 18 surface-to-air-missile battalions, and naval units with around 40 missile boats and 24 submarines, as well as several destroyers and frigates. Its material and personnel contribution even just to NATO’s land forces and integrated air defence in Central Europe amounted to around 50 percent. This meant that, during the Cold War, by the 1970s, the Bundeswehr had already become the largest Western European armed forces after the United States armed forces in Europe – far ahead of the British and even the French armed forces. In peacetime, the Bundeswehr had 495,000 military personnel. In a war, it would have had access to 1.3 million military personnel by calling up reservists.”
