Birth tourism
Some countries do not allow their citizens to renounce their citizenship or only if the citizenship was acquired by birth there to non-citizen parents. In Argentina, Brazil, Ecuador, Peru, and Uruguay, voting is compulsory for citizens. In Bolivia, Brazil, Chile, Colombia, Cuba, Guatemala, Paraguay, and Venezuela, military service is mandatory.
Election
Ballots in a show election may contain only one "yes" option. In the case of a simple "yes or no" question, people who pick "no" are often persecuted, thus making the "yes" choice the only option. An example of this is the elections of the People's Parliaments in Estonia, Latvia, and Lithuania in 1940 shortly after the Soviet occupation of the Baltic states; where those who voted received stamps in their passport for voting and those who did not vote did not receive stamps and were persecuted as enemies of the people. Another example is in contemporary North Korea.
