Why is your country's current extent and size optimal? Why not split it up, maybe even down to sovereign towns?
Why not unify it with one of your neighbours?
For example after 45 years of in-fact occupation by the Soviets people here won't easily accept censorship and wrong-think laws. Those things are too fresh in memory. It might be easier for our politician to vote for that in EU parliament when they are safely away from home (they didn't from what I understand) but they would think twice voting for it here.
Another thing is that people follow country level politics much closer than they follow EU politics which seems to be very detached. What usually happen is "GDPR got voted in EU, we need to adjust our laws" without any kind of public discussion about if we even want that law to begin with.
It may work somewhat better in USA where at least there is one language and some common element in education system (history, civics etc.). Here it just seems that People's Party Committeein in Brussels is making up laws and we are supposed to just accept it.
That is an omission of your politicians for not involving the public into the discussions, as there certainly are deep debates at the EU level that your elected politicians participate in.
And don't critisize the King or the Military. 'cause you might encounter what real consorship looks like. Unlike the EU, Thailand actually has censorship laws.
It might be better and cheaper to try to improve the place you live one step at the time. This assumes you live in the EU, there are worse places for which this might not hold.
Doesn't happen.
