Come here, buddy. Auto-translated

Situation: You were born in country A and spent your first 18-25 years there; all or most of your ancestors were residents of this country. After that, you moved to country B and settled there: you obtained citizenship and a good job, made many friends, and got married (optional), and you had children (optional). You lived there for some time, and then one day, a war breaks out between country A and country B.
The armed forces (taking into account the help of allies) are approximately equal. The economic situation was (and will be, in the event of a victory or a "draw") significantly better in country B.
Available options:
1. Stay (with your family) in country B.
2. Return to country A (the safety of the flight is guaranteed; you can take your family with you).
3. Move (with your family) to a third country and wait out the war. The financial situation is the same as in country A.

Are you thinking about moving?

It depends on the reason I left A. If they introduced some liberal laws there, while B has conservatism and Orthodoxy, then I'm for B. But if these countries differ only in their economies, then I'll most likely return to A. However, I wouldn't have left A in the first place.

If they implemented some liberal laws there, while faction B has conservatism and Orthodoxy, then I'm for faction B.

That's right! Let's say NO to liberal dictatorship and the violation of the right to slavery!

Maybe I am a coward, a scoundrel, and a villain, but in the event of a fair war, I would most likely prioritize the safety of the people closest to me (and myself, I wasn't born to be cannon fodder). So, if there were such an option, haha, then option 3 would probably be the best. Otherwise, I don't even know, I don't see much difference between the first two, and the economy in both cases will collapse to zero in the event of equal opposition.

I wasn't born to be cannon fodder.

Where does this confidence come from?

I am a coward, a scoundrel, and a villain.

We already know that.

I think a combination of Alex's and Heroist's answers is needed. So, first of all, you need to ensure the safety of your family by sending them to country B, where everything is peaceful and calm. Then, you need to decide: what connects you to country A, besides your place of birth? What connects you to country B, besides material well-being? Is this a war for the satisfaction of some not-so-"high" interests of countries A and B, or is it a war for survival, when the aggressor country really poses a serious threat to another country and, in the more distant perspective, to other countries as well? Depending on the answer to these questions, you can participate in the war on the side of A (more likely), B (less likely), or not participate in the war at all, leaving for your family in country B. I will add that if you decide to participate in the war, it is not necessary to do so with a rifle in your hands; you can help the front in various ways, for example, by organizing production; you need to decide where you will be more useful. I will also add that if country A = Russia and country B = a NATO country, then you don't need to think about this dilemma at all; the war will end in a couple of hours.

I agree, Menti; I would surrender immediately in that scenario.

From a camel.

We already know that.

That's good.

On the contrary. But yes, it's a pity for the NATO forces; they will be quickly destroyed by blessed missiles.

I give the order to launch my missiles at my own cities, and then I'm leaving to live in the west; it's not for nothing that I keep my finances there.

Oh, Revan, you shouldn't be giving them such ideas...

Hero, you underestimate the power of the Dark Side.
