1) you can only place influence in countries you have influence in when the turn starts and/or are adjacent to countries where you already have influence. If placing influence in a coutry where your opponent have control you have to place 2 influence until you have broken control. So if your opponent has 3 influence in a stability 2-country you will have to pay 4 influence to place 2 influence points.
This if I use a card for operation point, but if I use it as event it's the same?
Italian rulebook 6.1.1 states "the marker placed after an Event aren't subject to adjacency restriction"???
Probably I have not explaned well, or I have always played wrongly
