With a PoD after 1700, have a Germany today that fulfills these criteria:
-has a constitutional monarchy and nobility, similar to the UK.
-has at least its 1871 borders (bonus for also having Longwy, Briey, Belfort, Teschen Silesia, New Silesia, South Prussia/New East Prussia, German Bohemia/Sudetenland (German Moravia), Austria+Ödenburg+Preßburg+Marburg an der Drau, South Tyrol, or any combination thereof)
-has protection of civil rights on par with the UK and/or the USA (freedom of speech, religion, press, etc)
-bonus if the monarch is head of gov't and state and not just a figurehead, but still has limited powers (no suspension of rights, for example)
-this Germany must not have caused any world wars in the late 19th to early 20th century, and be the ally of the UK in any conflict with France and/or Russia, and never caused any genocides
- bonus if this Germany retains any overseas possessions to this day as territories or integrated states
-some form of Poland must exist also, as a stable and peaceful (today) nation, and no German state has a restless Polish majority.
-bonus if former colonies have today an ethnic German majority and are also peaceful, stable, prosperous countries where the German monarch is also their monarch.
