What is the real reason for the war between Russia and Ukraine ?.

The dispute between Russia and Ukraine is not fresh. Its roots are very deep. Indeed, Russia and Ukraine were part of the Soviet Union. After the dissolution of the Soviet Union, relations between Russia and the United States remained at odds, but the independent states adjacent to Europe came closer to the Western countries and America. Russia did not like the proximity of European countries and America to the states that became independent from the Soviet Union. This dispute deepened in the fight for the supremacy of America and Russia. On the other hand, Russia does not like the proximity of Ukraine and NATO. Due to this also Russia has tightened its position on Ukraine. Let us know what else is at the root of the dispute between Russia and Ukraine.

1. Ukraine is bordered by Europe to the west and Russia to the east. Until 1991, Ukraine was part of the erstwhile Soviet Union.
2. Tensions between Russia and Ukraine began in November 2013 when Viktor Yanukovich, the then President of Ukraine, began protesting in Kiev. While he had the support of Russia.
3. Yanukovich had to flee the country in February 2014 due to protests by US-UK backed protesters.
4. Angered by this, Russia annexed Crimea in southern Ukraine. After this he supported the separatists there. These separatists occupied large parts of eastern Ukraine.
5. Since 2014, pro-Russian separatists and Ukrainian forces have been fighting in the Donbass province.

6. Even before this, when Ukraine broke away from the Soviet Union in 1991, there were many conflicts between the two countries over Crimea.
7. After 2014, Western countries took the initiative to prevent the constant tension and conflict in Russia and Ukraine and to establish peace. France and Germany signed a peace and ceasefire agreement between the two in 2015 in Minsk, the capital of Belarus.
8. Recently Ukraine began to build close and friendship with NATO. Ukraine has good relations with NATO. NATO ie 'North Atlantic Treaty Organization' was created in 1949 to deal with the then Soviet Union. Ukraine's close proximity to NATO began to exasperate Russia.
9. 30 countries of the world including America and Britain are members of NATO. If a country attacks a third country, then all the member countries of NATO unite and fight it. Russia wants NATO not to expand itself. President Putin was putting pressure on Ukraine and Western countries regarding this demand.
10. After all, Russia attacked Ukraine on Thursday, regardless of the sanctions of America and other countries. Now if NATO retaliates on Russia and other countries  of Europe join this war, then the risk of third world war will increase.
