Sad that you have to go, even though we disagreed. You made good point, but the reason Byelorussia could do so well was it wasn't particularly involved in WW3, while Russia and Poland were, so it had an advantage.
I'll do international relations too:
Neo Byzantines: Stable allies due to the shared glory of the Orthodox Religion, and approving of the combat methods used by Byzantine military. They hope to work together in the future.
Neo Hungaria: Byelorussia notes with concern the great strength of the Hungarians, but for the time being has no quarrel with the nation, despite its heavily dictatorial, possibly corrupt government. The Byelorussians would accept not absorbing their territory, as there is other land to be had elsewhere.
Russia: The Russians hold a burning hatred for the Byelorussians, but Byelorussia is not afraid of their crippled enemy. They still hold dreams of conquering Moscow.
Finland: Tensions are high with the Finns, especially over the Leningrad Oblast border. It is expected a war is coming soon.
Iranian Republic: Appreciative of military capability, but otherwise has no real opinion.
American Patriots: Disapproval of the Facist system in place does not leave the Byelorussians looking well on the new Americans, but distance makes this matter less important.
Germany: The Germans are terrified of Byelorussia, given their weakened state after WWIII. Byelorussia has intentions to capture their land eventually.
