Polish in what sense? German in what sense?
many poles who came to America were called german since germany controlled the area. they hmay have been polish.. but considered german.. those on the other side were considered Russian as there was no Poland in any political reality
@Hvalrossen too some extent yes. especially if it was Islamic. Islamic automatically means non western. would be like being Japanese .. no matter how hard they tried and adapted and adopted .. they were still Asian. not saying its right or correct by any means. but during this time frame it is what it was.
@Colonel Zoidberg
biggest problem is no matter what the west gets the bomb by war start its too late for any real pod. we just drop bombs, why waste the lives of our troops.. as horrendous as that sounds.. multitudes die due to the effects. again .. something I don't condone. but at the time was the more than likely option.
and in Europe we were already over the rhine and well into germany by the time soviets were. getting to berlin was the only end game. if this drags on I would expect the west to show force.
the big differentiator here is up until and I would say even before to an extent the soviet union, Russia was considered an inbetween land. western.. but not. this was magnified by the soviet union .. which in most respects was a completely western under the communist framework. granted different at the governmental level and the firs 30 years of its existence. but in reality the people were not that much different when you talk average European Russian, Ukrainian, Belarusian or Baltic peoples.
Western is a state of mind like racism its meant to make a group feel better and more apart of a "tribe"
sort of like how in America you are white, ""African"-American". Native American, "Hispanic" ( how did spain get kicked out of the white club? .. oh I know. the muslim influence and then the well they were the super power and now are not club "
Western ideals and notions of society are biased and flawed like most others and exclude people as needed or wanted. again.. not that I agree with a lot of things either since everything is black and white.
what is western.. oh French ideals of democracy.. eh.. when? where? the french revolution and napoleon? hmm.. military take over .. emperor . French monarchy? british monarchy? Spanish? german states? the USA? uhm.. apartheid state until the 1960's at best .. at worst a full on racist state that had to have a civil war where millions died for equality that was in reality only on paper.
the west is just as flawed humans will always be the same crap species we are until we eventually drive ourselves to our inevitable self extinction due to our excessive greed and self loathing hatred of each other.
To answer the OP though.. yes it is possible. Make the Germans more hated. up until WW II the Germans were not hated. The Germans before 1870 were just a collection of small states an no threat. many nations married into and out of their families. ( matter of fact all of them )
you would need the Germans to be a united threat to what is the balance of power and to be socially isolated such as the soviets. ( socially they were not any different, western propaganda painted the average Soviet as something they were not )
Germans where not a threat to said balance until 1914 , and even then after the war they were not vilified to an extent that was harmful. WWII made german look pretty major screwed up but with really cool uniforms … the cold war and the soviets calmed that.
If the Russians were not under the soviets they would have been considered more western, I assure you. they are pretty much as white as it gets and socially very European.
I don't want to be misconstrued as I think western is a state of mind and an ideal and think many try to adapt that notion to their own way. But saying that the germans would be non western would require a POD pre 800 AD and you would have to hand wave away famines and wars and political instability that made Germans move in mass more than any other to the USA ( which became the number one super power and the sort of upstart standard bearer .. especially after ww I )
even Poland is considered western and the Baltics ..
Russia gets the boot because of communism and the cold war and well. convenient political enemy for he industrial military complex.
Africa wouldn't be because of racism and religion.. asia because of racism ..
mexico, latin America.. to much interbreeding makes them not cool to those from the north, plus the whole Spanish thing. basically being western is racism

its not about democracy, or capitalism ( money ) . its about being apart of a club of shared heritage and till being considered cool along the way. German came the closest to being expelled from the club in 1945, they did everything in their power to and have continued to do so to show that the insanity was temporary and to attempt attornment that will take another 80-100 years to start fade from memory. Western powers were shocked and disgusted by WW II and the sheer industrial level of barbarity that took place, racism that made even the USA say.. wtf man.. that's screwed up.. White people trying to utterly exterminate white people?! holy crap! .. hey they were Jews and Poles and Slavs. <the world.. wait. they where white people.. normal.. jew.. slav.. german.. what ever. this makes no sense .. > it toally blew their collective minds.
before the germans were just well. Germans. ambitious but not alien.. Nazis made them alien. so you want to make the germans non western? have the German Empire start off in such a manner. Have them expel in mass, treat minorities as cattle ( they did .. but no where to the extent the mazis did) have them genocide and persecute people based on religion or simple idea of being slav or some fool crap.
Other wise they are just another nation dealing with a population in a civilized for the time manner
this is the nation of culture and integral to western society for over a 1000 years.its going to be hard to make them non western
