Everyone declares war on me

[polarnik]

When I play as Greece and invade Turkey in turn 3/4 everyone declares war on me. For some reason when I restarted and tried it again on turn 6 Germany (the only nation that was actualy hostile to me) was the only nation that didn't declare war on me

Any way to avoid this or to change something in the files?

Go to the 1940 Euro scenario folder (I presume you mean this scenario)

Find in DefinesEuro1940.lua - line ~418

Spoiler :

[TURKEY] = {FRANCE, ENGLAND, GERMANY, ITALY, USSR, GREECE },

and delete the line.

Thus resulting in this..

Spoiler :

[SWEDEN] = {FRANCE, ENGLAND, GERMANY, },
[BALTIC] = {USSR},

Also in that section there's a list of other city states that are protected by the main civs in there, delete lines as you wish.
