Ukraine is a former ally of Russia, so Russia does not want Ukraine to disintegrate. If Ukraine disintegrates, countries led by the United States can control Russia through the disintegrated Ukraine. While controlling Ukraine, the United States not only increased its own strength and control over Europe. So Russia is very passive.

When the Soviet Union disintegrated, it was also the time when Russia collapsed. Since then, Russia has never made Ukraine independent. Since that day, Russia has been manipulating the political situation in Ukraine, using the democratic system to support pro-Russian Kuchma, driving away the disobedient first president of Ukraine, and fooling Ukraine into giving up nuclear weapons. Russia, not the United States, should be most worried. Oil prices are high, Russia's national strength has recovered, and Ukraine will not be spared.

Ukraine is the same to the west and the east, and it is doomed to failure. Anyway, Ukraine can't be better than it, because Russia can't sleep. Russia must not see a powerful country that can be equal to itself, appearing next to its own country. Because once such a country appears, the revival of Russia will never be realized in a dream. Once Ukraine is found to have deviant behavior.

In fact, when the Soviet Union disintegrated, Russia did not keep Ukraine, so Ukraine became independent. But it is not easy for western countries to disintegrate Ukraine now, even though Russia is still useful to Ukraine now. Of course, if Ukraine disintegrates, it will still be good for Russia.
