I see your points but, with all the political options and wars being fought at the same time
it becomes very complicated.
I think the best resolution is this.
UK .. has max 3 major 2 minor diplo chits for example, now if UK buys a chit for USSR it should only have a 4%
especially given the fact that USSR is being beligerent to finns baltics besserabia
now USSR launches winter war .. ok the nations that border finland, sweden, norway, baltics should all swing towards
the Axis by a % amount
If UK buys a USA chit its 5% .. If UK buys a spanish chit its 4% If france buys a spanish cit its 3%
why because spain is a pro axis influenced nation as well as the allies lost the SCW .. spanish civil war
Now, when USSR invades poland, hungary and the baltics both swing a % towards axis
when besserabia is annexed hungary and rumania both swing towards axis by %
Yugo was actually pro axis influenced, as well as in reality it was a pro axis coup followed by a pro allied coup
Italian and german chits would both effect yugo by 5%, and if yugo sides with axis, both huns and rums swing a % axis
why because they border axis
Now this may sound complex but its easy to figure out, take each situation and have a solution
lots more thoughts on this ... !!!
