It sounds like you want to stick around and be part of the resistance if the Russians try to annex Latvia again.
You're young. It's your homeland, and you probably feel honor bound by patriotism to do so.
With how the Soviets treated Latvia the last go around, rounding up tens of thousands, to send to Gulags in Siberia, to put down the resistance last time, there's undoubtedly some old stories which are very frightening.
This leaves you torn and conflicted between what you view as your "duty" and fear over what would happen to your family.
I know Jeff said to not get in to politics - and I will try to avoid this, but let's look at this tangent and assume Russia re-integrates Latvia to bring the 15% or so "non-citizens" you have, back in to their "loving care", where does that leave you? You aren't going to fight Mother Russia with a .357 handgun out in the woods. Well, you might, but it won't last long. Americans tend to believe that all you need is a rifle and a strong will, and you'll prevail against any odds.
But in America we have 300 million people, and even more guns than we have people, in private hands. Any occupying force would have "half globe" long supply lines to contend with. So here, it might be true. Rednecks with rifles would prevail even if our military was left in ruins.
But Latvia lacks the manpower and armament to be more than a tickle in the underbelly of Russia, who wouldn't have to contend with long supply lines, but rather, very very short ones, especially given that they'd be occupying a country where (just a short time before; e.g. currently) some 15% of the population weren't even considered "citizens" because they didn't have true Latvian heritage, but were instead descended from Russian blood lines.
Think about that. Right from the onset, 30% (give or take) of your population would be very much in line with Russia re-integration as ethnic Russians, and half of those (15%) would be very much in line because they aren't even citizens and don't even get to vote today! You've got a second class citizenry.
To the US folks, where minorities, women, everyone gets a vote (even dead people and illegal aliens in certain jurisdictions
), the thought of having a subjugated class without a say in anything is somewhat appalling.
The ethical merit of such a debate is only tangential, but it does bear weight in this discussion of revolutionary partisan - at least 30% of your country, from the very onset, is going to rapidly become "the enemy" in that they support the new Mother Russia overseers.
That is a *LOT* of eyes on everything. If the sheer weight of Russia's military might and the closeness (proximity) to Russia proper with the short supply lines weren't enough of a factor, that's the nail in the coffin of any potential resistance movement.
My advise is to get the thoughts of "glorious resistance" right out of your head, and quick, because any resistance in Latvia, with the sheer number of ethnic Russians and subjugated class, will be quashed before it's even born, and membership in an active resistance cell will be a very short lived and bloody experience.
And even if it's not? Even if organization is made so that you are able to take action? You'd be shooting your neighbors, fellow countrymen, those 30% ethnic russians, 50% of which are subjugated and currently non-citizens, many of whom who would be very supporting of a regime change.
That's a tough pill to swallow.
Regarding thoughts of emigration to another country, there's a lot of potentials. The good old USA is .. maybe not the best choice, for numerous reasons. Business is cutthroat here, highly competitive. Things are not easy even if you are brilliant in your career. We've offshored a massive amount of our labor and the remaining white collar jobs are incredibly competitive. High unemployment for so long has changed the feeling of the workplace.
Plus, you'd be cut to death by 1,001 taxes. It's hard to get ahead here. Hell, it's hard to keep your head above water, here!
I'd leave every option on the table, you have time to choose a more suitable home for your future generations of offspring. There's plenty of good choices out there which would be easier on you and your family, that wouldn't set you back so far.
