 Responding to international concerns about Russia's legislation, Putin asked critics to note that the law was a "ban on the propaganda of pedophilia and homosexuality" and he stated that homosexual visitors to the 2014 Winter Olympics should "leave the children in peace" but denied there was any "professional, career or social discrimination" against homosexuals in Russia.On 22 February 2014, the Yanukovych government of Ukraine collapsed as a result of the 2014 Ukrainian revolution, which the Russian government called a foreign backed proxy movement.On the same day, according to Russian president Vladimir Putin, he called an all-night meeting of his military leaders, at the end of which he ordered them to “begin the work to bring Crimea back into Russia.” By February 27, unmarked Russian troops in Ukraine were establishing a blockade of the borders and Ukrainian military bases in the Autonomous Republic of Crimea, and took armed control of its regional parliament.
