I think we'll need Guardian G.I. to clear that up for us. Guardian, do you imagine such a thing could ever happen in Belarus? Zhivye Belarus? Abo zhivye novy, nevyaliki, SSR...
Out of interest, does the Opposition in Belarus favour a return of the Belarusian Democratic Republic and its government in exile?
Our opposition constantly tries to do that at every presidential elections. After the preliminary results are announced (guess the winning candidate), around 8-10 thousand opposition supporters gather in the centre of Minsk, our capital city. The opposition agitators start telling people to go to this political demonstration
long before the election day. After they assemble, they start demanding President Lukashenko's resignation and try to do something drastic (like setting up a Maidan-style camp in 2006 or trying to storm the parliament building in 2010). Then the riot police arrive and clear the streets while foreign journalists film them. The European Commission, the US Department of State and all progressive mankind obviously condemn this grave and horrible violation of human rights the next day and renew the sanctions against President Lukashenko. At the next elections, it all repeats again.
The demonstrations generally only happen in Minsk, the city with the highest percentage of people supporting the opposition. Their popular support in the smaller towns is low. You can hardly find an opposition supporter in the countryside.
The biggest opposition rally against Lukashenko's presidency occurred in 1998, when he tried to dissolve the liberal pro-Western parliament, the Supreme Soviet of Belarus by the means of constitutional reform (he eventually succeeded). IIRC, around 30-50 thousand people took part in it. It also happened exclusively in Minsk. The popular support for the opposition has dwindled since then.
The opposition doesn't support the BNR's government in exile.
