Jospeh: please reread my posts again. I clearly stated since WW1 yidden stopped in Germany for ethical reasons. Did all shuls stop, I do not know. What we DO know is Jews did davven for the Czar even during pogroms and forced conscription of their children to the army. That is an historical fact.
The halacha is to davven for your own goverment first. The RZ k owns that. However, achainu kol bais yisroel…..when your brother is in harms way, you should davvens for their safety. If the Russian army has mostly jews, then yes, davven for them too. However, Israel has the largest army of Jews, and one ahould davven for them, especially if you are sitting and learning as they are protecting you.
