Yes, we can agree to disagree!

One last comment: In my posts (or even thoughts) I have not taken the country of citizenship to be synonymous with motherland. Motherland would be the country I was born in, but the country of citizenship could be different. All my arguments pertain to the country of which you hold a citizenship (and I have assumed you do not have dual citizenship). This is why I referred to the citizenship of the USA where cases of immigrant population becoming citizens are much higher than many other countries.

That reminds me: There must have been several people who defected from/deserted their motherlands, countries from Eastern Europe and sought asylum in the UK, US or Canada. Isn't that an example of people exercising their choice regarding government policies?

Yes, it's not easy when it comes to an individual and specific circumstances, but it can be done. Maybe there are ten people who were forced to put up with oppressive regimes for each one who defected, but the one who defected did get to exercise his right of abandoning the regime that didn't represent his views. So while it's difficult, maybe extremely, it's not completely impossible.
