This may or may not be a realistic goal, but if we do intend to invade France, and in the probable case that the Allies help France, the Allies, then we are to plan and organize massive armies to invade these countries. Here's what I plan on doing: Italy, Germany and I (Byzantium) will start and enact a coalition campaign on France. Russia and Sweden are likely next after this. In this case, an alliance-wide coalition against these powers will occur. I personally plan on taking land from the Caucasus and Germany probably wants more land than Poland. Britain, providing all goes well for the Central powers, will become a protectorate of Germany
