Passage: Belarus is a presidential republic, governed by a president and the National Assembly. The term for each presidency is five years. Under the 1994 constitution, the president could serve for only two terms as president, but a change in the constitution in 2004 eliminated term limits. Alexander Lukashenko has been the president of Belarus since 1994. In 1996, Lukashenko called for a controversial vote to extend the presidential term from five to seven years, and as a result the election that was supposed to occur in 1999 was pushed back to 2001. The referendum on the extension was denounced as a "fantastic" fake by the chief electoral officer, Viktar Hanchar, who was removed from the office for official matters only during the campaign. The National Assembly is a bicameral parliament comprising the 110-member House of Representatives (the lower house) and the 64-member Council of the Republic (the upper house).

Question: What nation is Alexander Lukashenko the leader of?
