Winston Churchill once described Russia as “a riddle wrapped in a mystery（谜） inside a puzzle”. Observers of Russia in the 21st century could surely say the same of the country’s president, Vladimir Putin.
Born in Leningrad, six months before the death of Stalin, the young Putin experienced a poverty-stricken childhood but received a good education. He developed lifelong interests in judo and spy novels, and first applied to the KGB(苏联国家安全委员会) at the age of 17. When they told him to go away and come back with a degree, he completed with an efficiency(效率) that would later serve him well.
Putin used his KGB training, plus his own discipline and common sense, in a series of jobs. He became acting President on 31 December 1999, when president Boris Yeltsin resigned in a surprising move. Putin won the 2000 presidential election and in 2004 he was re-elected for a second term lasting until 7 May 2008.
Due to term limits, Putin was unable to run for a third presidential term. After the victory of Dmitry Medvedev, in the 2008 presidential elections, he was appointed to be Russia’s Prime Minister.
Putin is regarded as one bringing political stability and re-establishing the rule of law. During his presidency, Russia’s economy(经济) bounced back, seeing GDP increase by 72%, poverty cut more than half, and average monthly salaries increase from $80 to $640. Analysts have described Putin's economic reforms as impressive. At the same time, his conduct in office has been questioned by political opposition at home, foreign governments, and human rights organizations for leading the Second Chechen War, and for his record on human rights and freedoms.
Whether he wants to drive
Russia into a new stage, or believes in the values of its Soviet past, he is determined to put his nation back on its feet. To do this, Vladimir Putin may have to show his true colors sooner rather than later.
