We that to Japan...
Darn it... We did that to Japan.
We defeated and occupied Japan. Russia will have to defeat and occupy Ukraine. Difficult to do when a few kilometers costs them tens of thousands of casualties, considerable damage to their Black Sea fleet and Russia’s infrastructure.
The German army was restricted to 100,000 men; the general staff was eliminated; the manufacture of armoured cars, tanks, submarines, airplanes, and poison gas was forbidden; and only a small number of specified factories could make weapons or munitions. All of Germany west of the Rhine and up to 30 miles (50 km) east of it was to be a demilitarized zone. The forced disarmament of Germany, it was hoped, would be accompanied by voluntary disarmament in other nations.
The Potsdam Agreement, after WWII, included the following:
4. Disposal of the German Navy and merchant marine.
All but thirty submarines to be sunk and the rest of the German Navy was to be divided equally between the three powers.
The German merchant marine was to be divided equally between the three powers, and they would distribute some of those ships to the other Allies. But until the end of the war with the Empire of Japan all the ships would remain under the authority of the Combined Shipping Adjustment Board and the United Maritime Authority.
