During the Soviet period, it can be said that Ukraine was regarded as a pearl in the palm of its hand, and a large number of military and scientific and technological resources were placed in Ukraine.
Is it because Ukrainian girls are pretty? No, not all...
An important reason is Ukraine's geographical location, sitting on the Black Sea bridgehead Crimea, and the Donbass Coal Mine, plus its own agricultural resources. If you want grain and grain, industry and industry, and military ports, it can be said that those who win Ukraine will get Eastern Europe.
Notice the two key words: Crimea and Donbass, which are strategic locations for Ukraine.
Crimea is a peninsula that stands out on the Black Sea, and the island of Sevastopol is the most suitable port for warships on the Black Sea (followed by Sochi), and the Soviet Union established a large industrial belt based on the Donbass Coal Mine
For both Tsarist Russia and the Soviet Union, building a fleet in the Black Sea was the best option. (Although the Bosphorus, out of the Black Sea, was in Ottoman hands.) )
Although the Soviet Union attached great importance to Ukraine, at the beginning of World War II, due to the personal command of Stalin, hundreds of thousands of Soviet main forces were completely annihilated by the German army at the Battle of Kiev.
This was followed by the famous battle for the fortress of Sevastopol between the strategic Crimea and the Soviets.

After annihilating 240,000 Soviet troops, the Germans finally completely occupied Ukraine and Crimea.
By 1944, the Soviets had assembled 470,000 men, 5,982 guns and mortars, 559 tanks and self-propelled guns, and 1,250 aircraft, and retaken Crimea with the support of the Black Sea Fleet and the Azov Sea Fleet.
The importance of this place is evident.
And some of the key sites mentioned above are also the key sites surrounding 2014 and this crisis.
When the Soviet Union collapsed in 1991, Russia, Ukraine, and Belarus were the first three countries to conclude the Cissembles and were iron allies in ending the Soviet Union. Ukraine and Russia, in particular, carved up the Soviet Black Sea Fleet and a number of nuclear weapons.
For a long time to come, although the three economies were not good, the relationship was maintained well. Ukraine leased Sevastopol to Russia for a long time as a military port.
But more than 60 percent of the Russian-speaking population in these areas. Although it belongs to Ukraine, the Majority of Russian Speakers pose a hidden danger of instability in eastern Ukraine and crimea.
