A thumbnail for a strategy game with real countries

You will be making a new thumbnail for the game. It can be about countries, or it can be like the other war related games. Those perform the best. I will be picking 5 people to do thumbnails for me. You have 3 days to complete the thumbnail you are making. Make something like in the references if you want, if you do adding the USA flag and UK is encouraged. If your thumbnail performs better than the others, you can make some more for me.
