According to the BBC News profile on Belarus (http://news.bbc.co.uk/2/hi/europe/country_profiles/1102180.stm)
"Over the years, several opposition politicians who might have provided leadership have disappeared or been imprisoned. Insulting the president, even in jest, carries a prison sentence."
Lukashenko is a paranoid nut. At this point he fears a free and fair government, since he suspects that the Belarussians might do to him what the Romanians did with Ceaucescu.
