This my paragraph was deleted by the moderator in my textbook "Interesting Social sciences," therefore I posted this article on this Political Forum. Reasons of war This operation is not yet completed, so it is not yet clear what the results of this operation will be and whose victory will be. This has so far prevented me from starting work on a description of this operation. This article will be supplemented in the future in accordance with the course of events in Ukraine. American intelligence supported the nationalist movement in Western Ukraine. The beginning of this movement is rooted in the events of World War II, when Ukrainian nationalists took part in the war on Hitler's side. Ukrainian nationalists formed the SS "Galicia" division and ukrainian nationalists waged a guerrilla war against the Soviet regime for about 10 years after the end of World War II. The USSR has won World War II and the USSR has suppressed this nationalist movement with great difficulty. The leader of this movement of Ukrainian nationalists was Stepan Bandera, who was killed eventually by Soviet intelligence officer Bogdan Staschinsky in Munich in 1959 with help of shot in the face with a pistol that sprayed a poisonous substance (potassium cyanide). President of Ukraine Viktor Yanukovych acted hesitantly and Viktor Yanukovych could not disperse Euromaidan in 2014. This ended by provocation with the shooting by snipers in Euromaidan. Armed participants of Euromaidan has gone on storm of the legal authorities and on illegally seize power. Viktor Yanukovych has fled to Russia. Crimea and Sevastopol have separated from Ukraine on the basis of a referendum after these events in 2014 voluntarily and Crimea and Sevastopol became by part of the Russian Federation. Russian troops helped this process. And civil war of Donetsk and Lugansk against the nationalist authorities of Ukraine has begun in the Donbass. The Donetsk and Lugansk republics have separated from Ukraine, Ukrainian troops were defeated by the armed police of these republics. The Russian Federation provided armed support to these republics. Peace agreements were signed in Minsk, which Ukraine did not fulfill actually. After these events, the United States have begun to openly provide economic and armed support to the nationalist government of Ukraine, the United States has begun to rearm of the Ukrainian army. The Ukrainian army fired of Donetsk and Lugansk during 8 years with impunity, that led to the death of a significant number of civilians, to the destruction of buildings. The nationalist government of Ukraine carried out terror and genocide against the Russian population inside Ukraine. Gazprom was forced to build gas pipelines bypassing Ukraine (North and Turkish Stream) in case of war to protect itself from the possibility of an explosion of a gas pipeline passing through Ukraine.Ukrainian nationalists have built a dam, ukrainian nationalists have disrupted the work of the North Crimean Canal and ukrainian nationalists have declared a water blockade of Crimea. The nationalist government forbade Russian-language teaching in schools, although Russian is native for a large part of Ukraine's population, especially in the East and South of Ukraine. These areas were donated by the Bolsheviks to Ukraine from Russia. Russia was forced to build the Crimean Bridge to have direct road and rail links between Russia and Crimea. Ukraine was negotiating aboot accession to NATO and the European Union, which did not suit categorically of the government of the Russian Federation. President Vladimir Vladimirovich Putin outlined the "red lines" where Ukraine should be included in Russia's sphere of influence.
