stated that the post-Soviet states are strategically vital to Russian interests. Some Russia experts have compared this concept to the Monroe Doctrine. A series of so-called colour revolutions in the post-Soviet states, namely the Rose Revolution in Georgia in 2003, the Orange Revolution in Ukraine in 2004 and the Tulip Revolution in Kyrgyzstan in 2005, led to frictions in the relations of those countries with Russia. In December 2004, Putin criticized the Rose and Orange revolutions, saying: "If you have permanent revolutions you risk plunging the post-Soviet space into endless conflict". Putin allegedly declared at a NATO-Russia summit in 2008 that if Ukraine joined NATO Russia could contend to annex the Ukrainian East and Crimea. At the summit, he told US President George W. Bush that "Ukraine is not even a state!" while the following year Putin referred to Ukraine as "Little Russia". Following the Revolution of Dignity in March 2014, the Russian Federation annexed Crimea. According to Putin, this was done because "Crimea has always been and remains an inseparable part of Russia". After the Russian annexation of Crimea, he said that Ukraine includes "regions of Russia's historic south" and "was created on a whim by the Bolsheviks". He went on to declare that the February 2014 ousting of Ukrainian President Viktor Yanukovych had been orchestrated by the West as an attempt to weaken Russia. "Our Western partners have crossed a line. They behaved rudely, irresponsibly and unprofessionally," he said, adding that the people who had come to power in Ukraine were "nationalists, neo-Nazis, Russophobes and anti-Semites". In a July 2014 speech during a Russian-supported armed insurgency in Eastern Ukraine, Putin stated he would use Russia's "entire arsenal of available means" up to "operations under international humanitarian law and the right of self-defence" to protect Russian speakers outside Russia. With the attainment of autocephaly by the Ukrainian Orthodox Church in December 2018 and subsequent schism of the Russian Orthodox Church from Constantinople, a number of experts came to the conclusion that Putin's policy of forceful engagement in post-Soviet republics significantly backfired on him, leading to a situation where he "annexed Crimea, but lost Ukraine", and provoked a much more cautious approach to Russia among other post-Soviet countries. In late August 2014, Putin stated: "People who have their own views on history and the history of our country may argue with me, but it seems to me that the Russian
