Trump wins Russia, Poland, Hungary, and various other countries in the region. Eastern Europe is a good region for Trump. Ukraine is hard to say, as they would care about the Hunter Biden scandal, but obviously they oppose Russia.
A third party comes out of nowhere to win most Middle Eastern countries, a Muslim theocrat. Said candidate does OK in Indonesia, but Biden probably eckes it out there. Iran goes for their own candidate. Trump wins Lebanon and narrowly Israel (he did move the embassy)
If Biden is winning in Muslim countries, he is winning Lebanon. At best, Trump probably wins the Christian vote.
