There are a lot of ethnic Poles in eastern Prussia. Germany would likely not want to antagonize them by helping a heavy handed response on IEF Poland. Also, the Russians get nothing by trying to hold on to their chunk of Poland. I could see the Motherland leadership cutting it off to hold on to more desirable territories and send more resources against the TechnateWhy would Poland be lost if the Germans were fully on board with helping the IEF in case a civil war occurs? Would they not oppose an independent Poland?
