Europe 40 second edition (not Global 40): opinions, strategies and advice

Hello everyone,
even if late, I started playing Europa 40 second edition. With my group we only started one game, completing only the first turn (I play the UK), without using the National Objectives (I think we will use them later). To do a bit of “practice” I played some games on Triple AAA (but there the National Objectives are always active and I don’t think there is a way to “deactivate” them … in fact I will be grateful to anyone who can give me some “tips” in this regard).

I hope this first post of mine can open a discussion on the strategies of Europe 40 and only Europe 40 (I opened a new post because everything I found around was about Global 40, which becomes much more complex: I want to see Europe and Pacific separately first to better understand the maps and strategies before diving into Global)
My first impression (but only as a first impression while it’s hot) is that the Axis is heavily favored (and, I repeat, I think that the National Objectives accentuate this advantage even more).

Germany has a disproportionate military potential in troops and the possibility it has of being able to declare war at will before the turns in which the USSR and the USA will enter the war anyway, puts it, in my opinion, in a position of further advantage. It has many strategic options (Sealion, Barbarossa) that make it not easily contained.
Of course, the AI ​​of Triple AAA did not help me to get a clear idea of ​​the balance of the game: when I played with the UK, the USA spent its time colonizing South America while the Germans took Moscow; when I played with the USA, the Soviets launched suicide attacks while the English colonized Africa and South America while Moscow fell. I will have to play games of Triple AAA using all three Allies, but I should first learn more about the game and its strategy.

I ask all the experts of the game and those who have played several games of Europa 40 to write down their impressions of the game, what are the most effective short and long term strategies with each power and, of course, the initial openings with each power and the related purchases.

Thanks in advance to everyone.

@Panther ok, thanks for the clarification, then we will restart the game with the National Objectives (since they are not optional, like in the Anniversary edition, for example). I hope someone can give some strategic and tactical advice on the game.
