Actually, I have only recently discovered that 10 spies internally and lower neutrality helps considerably. I started out using counter espionage and only recently changed it, which can go some way to explain the delay I expect. Does it really move that quickly though? I swear I've had this set since 1942 and it is only now beginning to lower. I'm at 43%.
Brazil starts at 80%.
Britain is at 33% towards me with a threat level of 11.
