Do you know, why Russia is dangerous? Can you give me your opinion about my analysis of current situation in Russia?

Putin needs to hold and increase his power in Russia. Why? Else he (and his friends) can lost his billions, property, freedom and lives. Putin is afraid Gaddafi fate. And now he is losing power. To keep it he needs wars in Ukraine, Syria, N Korea, social unrest and/or allies in western countries. He needs conflicts. Russian natural resources economy is falling quickly. Russia has no technologies, industry. She has only sanctions from USA and EU, big army, high level secret services and poor angry citizens. Only terror and lie can save Putin's power.

Putin begun invasion in Ukraine because Revolution has happened in Kiev. Revolutions are like virus. They spread in same regimes countries. Ukraine and Russia had similar regimes. Putin needed counter-revolution in Ukraine, to prevent Revolution in Moscow. Also, he needed to back control of Russian main colony - Ukraine (long story). And Revolution in Kiev was a good occasion to implement invasion plans. But this is not a primary target. He failed many times in Ukraine company. And now he has not very good situation.
