Where did you get the "Jews did not fight" claim? There were ~100,000 jews in the german army in WWI
Searching for "Judeopolonia" I get a 19th century anti-semetic conspiracy theory, which makes me less interested in digging into it.
In german army.We are taking about russian and polish jews.Neither of them fought well.Plan was for 29-30 million people state with 2 million germans and 6 millions jews as superior races,and others as underhumans.\It was proposed in 1914 by Komitee zur Befreiung der Ostjuden ,as one big Pufferstaat,but becouse it would mean that all poles and most ukrainians would fight them,german abadonned it and followed with "free"Ukraine and puppep Poland.
Germans,being led by prussians,do not even thought about giving back what they stolen from Poland and deal in honest manner.
Which cut only source of recruits who would fight - Poland.
Good,that lost thanks to that and other mistakes.
Second coming of Judeopolonia was 1920,when soviets come with"polish" goverment made mainly from jews.They lost.
Unfortunatelly,they win in 1945 - only dumb polish cryminals supported them,good for removing nails and nothing more.
Soviets must provided their own people to rule - or polish jews.They ruled till 1956.
In 1968 dumb commie poles removed them from power,but not hurt in any manner - those who leave could,for example,take 4kg of silver , 25 painting and many other things per family.Officers who worked for Izrael could go there - if they were soviets,they woud end in gulag.
They leaved and their descendents tell to our days how bad poles hurt them - when their polish victims go to massgraves or must leave their homes without nothing.
P.S if you knew polish - Judeopolonia,żydowskie państwo w państwie polskim.Andrzej Szczęśniak,Polwen 2001.
