WI - Geopolitical implications of a neutral post-WW2 Germany

Shortly after WW2, Stalin proposed to the Western allies the idea of a united Germany, with the condition that the resulting state would not join neither NATO nor the Warsaw Pact. Due to fears of Stalin's deal being a plot, and the threat of German communists potentially subverting the neutral country into a red whole from within, the West did not go along with said proposal. But let's suppose they do - how does a neutral, capitalist Germany affect European geopolitics, or the Cold War in general?
 
The livelier economy of the west means that Wessis dominate the country and while tensions are much lower since NATO and the WarPac don't touch as much now, Germany probably turns to a Sweden type situation where they are offically neutral, but will back the west should push come to shove.

That being said, this will probably do much to relieve tensions and we might see a tamer cold war
 
A much quieter world. Germany remains a neutral country, fully debellated and without an army, with some limited, sparse (non-territorial; no more "zones of occupation", but shared "defense"/control burden) military presence from all WWII victors, "just in case". Its governments will very likely oscillate from liberal-conservative to strongly social-democrat. Communists are obviously allowed and receive a fair share of votes, as under Weimar. The economy, in shambles initially, recovers, a bit less brilliantly than OTL, but by the Seventies it's clear that Germany as a powerhouse is back, and back to stay.
 
Another question - could this somehow mean a chance for the now-neutral Germany and Austria to be united into a single state?
 
Might delay the onset of the Cold War for a few years. It was tensions over Germany that officially kicked things off. With a neutral Germany and Austria, as well as a possible Yugoslavia is the Tito-Stalin split still happens, there's a solid neutral bloc between the Soviet and Western powers. The Soviets would also benefit from having a reunified Germany paying them reparations for the war instead of stamping down on the poorer eastern third that they controlled IOTL. Germany could end up in the Non-Aligned Movement, which would give the Non-Aligned Bloc a major economic supporter.

In terms of government I suspect that the SPD would be main party of government, given that the territory that became East Germany was historically left-leaning and its mostly Protestant population would make it difficult for the de facto Catholic CDU to make significant inroads there. On the other hand with the vast majority of the expellees from over the Oder-Neisse Line now in a democratic Germany there would be a larger support base for the GB/BHE and subsequently a larger base for a right-wing nationalist party to exist, though the other parties would probably cooperate to marginalise them. Finally you would probably have a much more thorough Denazification as Cold War pressures caused both East and West Germany to abandon it.
 
The non-aligned, united Germany becomes a player in the developing world, leading the movement of countries in neither the Soviet East nor the Capitalist West.
 
Well, I'm not sure the Soviets or the Western Allies (France and to a lesser extent Britain, at least) would tolerate Germany getting involved in the Non-Aligned Movement, especially as during WWII, the Axis tried to get Asians and Middle Easterners to rebel against Britain, and also Germany taking leadership of anything big (even shared leadership with, say, India and China) would not fly well as memories of WWII are still fresh, and finally the Third World was seen as the French and British as their backyard, and by the Soviets as their future area of influence (to take), so Germany will get heavy pressure to remain just neutral. A good little neutral, that trades with everyone but stays away from big world affairs.
 
I always had a hard time believing Stalin on that promise, a huge force in soveat politics was in keeping Germany divided so as to never threaten Russia ever agean, and only allowed Germany to reunite do to it's own economic calpes.
