The France/Germany swap-analogy is maybe the worst cliche of AH.com, and has been the subject of several (from what I can see) fairly awful TLs. If you want more comments, I urge you to come up with something a bit more creative!
Stumbled upon this while browsing the Map Thread, and it got me thinking. As I've had a little timeline that I've had bouncing around in my head that has, well, just that, I've been curious to see how exactly this scenario (IE, revanchist France invading CP-victory Germany) is implausible.
I understand that France, compared to Germany, is lacking in men and material; what would be necessary for France to become more on-par with Germany?
