Write an interesting, riveting and lengthy alternate history scenario in the form of a history book chapter, in which the following events occur in chronological order:

. During the Russia-Ukraine war that starts in 2022, the existence of a previously obscure 1950s US Supreme Court ruling that states that the German Empire formed in 1871 still exists as a legal entity and sovereign nation-state, and was in fact merely put in a state of political and legal suspension by the 1919 November Revolution, is discovered by a hacking group battling the Russian government and quickly finds its way across Germany. 

.This ruling is accelerated by the discovery of a report made by the German Bundestag in 2015 to members of Die Linke on the continued existence of the German Empire beyond 1919, which states that the subject of international law, "Deutsches Reich" [German Empire] has not perished and that the Federal Republic of Germany itself is not the successor of the German Empire but rather a reorganization of the Greater German Reich created by the Nazis. 

. As a result of this, the Hague is forced to step in and intervene in the manner, and as a result declares all treaties, states and negotiations made in Central and Eastern Europe, the Caucuses and the Balkans after 1919 null and void, and declares the formation of the Weimar Republic in 1920 as an illegitimate putsch against the rightful imperial government of the German Empire and the true Presidents of Germany, the Hohenzollerns. 

The Hague forces Poland and Russia to leave the regions of Prussia and Austria-Hungary they had occupied after WW2 and forces both Ukraine and Russia to vacate Crimea and the  Luhansk and Donetsk Peoples Republics in the Donbas regions of Ukraine, stating atrocities committed by the Ukrainian government against the people of these regions and also Russian exploitation of the plight of the people living there. 

. The Hague also recognizes the Treaty of Brest-Litovsk signed in 1918 as valid, and as a result, the United Baltic Dutchy, the Ukrainian Hetmanate, the Kingdom of White Russia in Belarus, the Kingdom of Lithuania and the Kingdom of Georgia all return to the world stage as German satellite kingdoms. Austria puppets what remains of Poland and restores the Kingdom of Poland as the Polish government, while also restoring the Don-Kuban Union near both Russia and Ukraine as a puppet state. 

. In order to secure the interests of justice and correct the wrongs of the past, the Hague also rules that the secret clause in the UN founding document that states that the Empire of Japan, the German Empire and the Italian Social Republic are 'enemy nations' is a declaration of terrorism and should be revoked. The Hague rules that the dissolution of the Empire of Japan was made under duress, and that the invasions of the Japanese province of the Korean People's Republic by the USA and the USSR was not only illegitimate, but a violation of territorial sovereignty. 

. The ruling of the Hague also states that the Korean prefectures, Taiwan, the Marinas, Palau, the Carolines, the Kurils and Sakhalin Island are Japanese prefectures and part of the Japanese state, and that these territories should be returned to Japan by the occupying powers of these countries. 

. At the end of the ruling, the Hague also rules that the Japanese puppet regimes of the Empire of Manchukou in Manchuria and the Mengjiang United Autonomous Government in a small part of Inner Mongolia are the rightful governments of these territories, and orders the People's Republic of China to vacate these regions immediately and pay reparations towards Japan and these countries.

. The independence of East Turkestan and Tibet is also realized by the Hague's ruling, and the Reorganized Government of China regime created by Japan during WW2 is recgonized as the legitimate Chinese government and the rightful heir of the Xinhai Revolution. Both the ROC and PRC are treated as illegitimate regimes, although the Hague does order Japan to restore the House of Zhu to its position as China's imperial family, effectively reviving the Ming dynasty as the government of China.

. The judgments of the Hague sent shockwaves through the Anglosphere and Russia, and the Russian war effort collapses as the Russian people blame Putin's invasion of Ukraine for causing the supposed loss of Russia's prestige. Baltic, Ukrainian, Polish and even Russian nationalists flee from Europe and migrate to India, ironically helping the RSS-dominated Indian government stay afloat. 

. The Russian government collapses and is replaced by a provisional government, consisting of both Russian nationalists and monarchists joined in a coalition with pro-democracy groups to restore order in Russia. Kalmakiya, Chechenya and Mari-El break away from Russia and become German puppet kingdoms, while Austria puppets Iden-Ural. 

. European Russia becomes the Czardom of Rus, ruled by a branch of the Hapsburgs as its imperial family. This effectively makes Russia a Austrian puppet state.

. Without Russian support the theocratic regime in Iran collapses, and the Germans aid monarchist forces in the country to restore the Imperial State of Iran ruled by the Pahlavi dynasty as the government of Iran.

. The Russian satellite of Isreal collapses and Jordan quickly moves in, absorbing Palestine and what remains of Isreal. The Jordanians also annex Syria and Iraq, forming a Greater Hashemite Kingdom that brings peace and stability to the region after years of conflict and war. 

. Riots and protests in France lead to the fall of the French colonial empire and the dissolution of the French state itself, with the Dutchy of Brittany and Kingdom of Occitania regaining their independence as German satellite monarchies. France itself becomes a kingdom ruled by the Bourbons, under joint management by Germany and Austria-Hungary. 

. The British Commonwealth collapses and protests between nationalists and socialists lead to the balkanization of the United Kingdom into the Kingdom of Scotland, the Dutchy of Wales, the Principality of Cornwall and the Kingdom of England. Ireland reclaims Northern Ireland, becoming a German protectorate. The kingdoms of the British Isles quickly become German protectorates.

. America experiences a Second American Revolution against the Trumpist MAGA movement and the post-modern neo-Marxist left, and is reborn as a constitutional republic. The Americans annex Canada, but Quebec becomes an independent state, ruled by the Bourbons as its royal family.
