I personally think Stalin had a white jacket in the nut house with his name on it. I dont give him as much credit as say Lenin, i think things worked out for stalin as much be the circumstances and how they unfolded. And the question of whether or not nations should or should not invade each other should come down to the circumstances and how they play out. Perhaps in history the opportunity simply didnt present itself at that time to take this course of action, perhaps in one of our games (as i pointed out) the circumstances may dictate otherwise.
Remember also that Diplomacy is seriously lacking in the game, there are no real ongoing negotiations between nations, no threats made, counter threats, offers etc... we dont have the ability to really take advantage of all that.
My points are simple.
1) Stalin wasnt the most sane person in the world.
2) Nor the most trustworthy.
3) He wanted an empire.
4) The Soviets had a history of conflict with the Turks.
5) Stalin was interested in the middle east, turkey not only would help guard that flank but provide a mediteranean port.
6) Stalin clearly had animosity to the West so its likely if the circumstances were favorable he might be inclined to fight them.
Game issues;
7) IF Turkey appears undefended
8) IF the war is going well enough on all fronts that the Soviet Union is in no real danger
9) IF the allies appear weak and unable to resist his move into Turkey
Then and only then there would be a small (10%) chance he jumps in. Then you could modify that (10%) down or up depending on a variety of issues.
I cant say with 100% surety that i know for a fact there were absolutely no conditions where as Stalin would have invaded Turkey. If someone else can your special, so please give me the upcoming lotto numbers!
Even if it is considered a reach by some, i can at least make an argument for it based on the evidence at hand, as opposed to say justifying Albania conquering the world with Militia.... IMO its no more of a stretch then Nat Spain or Turkey joining the Axis which the game allows.
We need some variety, as long as its plausible im all for it. The Czechs didnt fight, but when that decision fires i dont feel like PI destroyed history, its definitely plausible, and as it should be its a small (10%) chance of occurrence.
