It is a very spicy question tbh and maybe the answer is no but still, what is your viewpoint from a historical viewpoint.
First of all, I don't like Nazis, I even would consider myself as being a leftist.
But that's just my standpoint, so back to my question.
First of all, yes the nazis lost WW2 but the nazis weren't germany and definitly weren't after war germany.
First of all, the question probably can only be answered in "parts" and not as a whole. Why? Because germany also wasn't a whole for quite some time after WW2.
The first big factor here would be the Marshall plan, which only West Germany received. This pretty much was the first step to make West Germany way more modern and also boost the economy, while east Germany only recieved the soviet help, which wasn't really that much worth.
Over the years east Germany became the workbench of west Germany (probably comparable to Chinas position on the market today in a sense)
There also were some "events" for/in west germany like the "Berlinkrisen" or the "Wirtschaftswunder"
Also west Germany was given very much freedom over time, they even were allowed to field a army on there own again. East germany also had a army, the "NVA" but they were still under soviet rule despite this, so basically east Germany was more like a Canon fodder spender and a very thought buffer between Moscow and the west If they would have braked through the eastern lines and hopefully nobody pressed the button to start the atom bombs.
After that there were some other major events like the "Wiedervereinigung" which basically just was west Germany re-occuping east Germany but never truly reunited both halfs under the actual term to also rewrite the constitution.
After that Germany just never stopped climbing the ladder.
And maybe the last major event was the "EU" in which germany now is the leading power.
First and foremost the assumptions that 'Nazis weren't Germany' is basically false, as the monopartisan system dominated by NSDAP was the legitimate government of the Germany that had prerogatives to declare war and use the available industrial and military resources. Of course, not all Germans supported the National Socialist government, but the Nazis were still acting in the name of the entire country.
Now, Germany definitely lost the war, and suffered heavily because of this. The damages and deaths suffered in the course of war including the Allied offensive in the German territory not withstanding, Germany lost a very large part of its pre-war area, more than half of total territory in 1939. First and foremost, the diplomatic annexations in 1938 were reversed, with the Sudetenland being returned to Czechoslovakia and Austria regaining its status as a sovereign country. Then, the entire Pomerania, remaining part of Pomerelia including Danzig Free City, Upper Silesia and Western of former Greater Poland were ceded to Poland. Eastern Prussia has been divided roughly in half, with the southern part being given to Poland and the northern part joining the USSR (today the latter forms a Russian exclave known as Kaliningrad Region). Last but not least, the provinces of Brandenburg, Meklemburg-Vorpommern, Saxony, Saxony-Anhalt and Thuringia were detached from Germany and given the new political identity as the German Democratic Republic (with the exception of the West Berlin enclave), essentially a satellite state of USSR. On top of all this, Germany was occupied and forced to pay extensive damages for the survivors of the invasion, even though Soviet intervention resulted in more or less official waiving the claims in the case of some of their new satellite countries.
Thus, Germany suffered tremendously as the result of their loss in the Second World War, but they managed to recover quickly mainly because of the new geopolitical order caused by the same conflict that brought the Third Reich down. Thanks to the agreements between the USA, UK and USSR drawn mainly during the conferences in Potsdam, Tehran and Yalta, USSR expanded politically, having establishing a firm control over the entire Central and South-Central Europe, or, as it was commonly said 'from Rostok to Vladivostok' (this has been challenged in the south after the Tito-Stalin split, but this is another story).
This expansion of the USSR that turned it from not so seriously treated country (in 1941 most military experts considered it to be unable to repel German invasion) to a global superpower matched only by USA. The presence of a communist and heavily militarist empire controlling large part of Europe forced 'West' to tighten the ranks, so to speak, what resulted in lifting the occupation of Germany and Austria, economic support rendered to these countries in the form of Marshall Plan and the creation of the united economical system that would alleviate territorial tensions, chiefly between France and Germany. This led to the proclamation of the European Coal and Steel Community in 1951, what opened the way to further integration, exemplified by the Treaty of Rome in 1957 that created European Economic Community that later was transformed into European Commonwealth and ultimately the European Union.
Thus, Germany suffered heavily as a result of the Second World War, but was able to recover thanks to their position as the border state in the new balance of power between largely democratic and capitalist 'West' and communist 'East'.
