I had serious trouble with norway in a match with a friend of me also. He was denmark, me norway, our airdefense was... not too good. If you play in this constelation against soviet-strong-decks then you might have no chance to do anything. Mi-28 have a greater range with their rockets then your anti-air units, you have no anti-radar-plane to kill their buks. Suck a situation is tremendous and to be honest i got no good answer for your so far. Obviously you have to hide your AA and usually, as soon as you have shoot down something from the enemy, relocate your anti-air or its doomed.
Vice versa you will have serious trouble against an average us-player as a minor-pact nation also.
So while the T80's overroll your sweet little leopards and the mig31 shoot down your "airforce" if they are not brought down bei buks you can't face strong enemys this way.
As i said:
relocate your anti-air after you think the enemy might know where they are
In general you cant play to offensive as minor nations most of the time if you want to win, build traps and invite them to drive in. And then kill em. Face to face its hopeless, but in ambushes minor nations tend to shine. Because when the enemys armor do not help them, when the airplanes flew over your airdefense without any harm just to get shoot down by the next flyover... Then your army will shine.
