The current situation in Ukraine is sadly similar to the situation in the Soviet Union when Nazi Germany attacked it on June 22, 1941.
Below is some history:
“For over eight hours after the German assault had begun in the early hours of 22 June, he (Stalin) still continued to restrict his troops’ response, hoping in vain that the attacks were an unsanctioned effort by German generals to provoke war. In keeping with this fear, a military dispatch (issued about 12:30 A.M.) ordered Soviet commanders “not to give way to provocative actions of any kind which might produce major complications. “Similarly, the general in charge of the Baltic region gave instructions at about 2:30 A.M. that included the following phrases: “In the case of provocative action by the Germans, fire not to be opened. In the event of flights by German aircraft over our territory, to make no demonstration and until such time as enemy aircraft undertake military operations, no fire to be opened on them. In the event of strong enemy forces undertaking offensive operations, to destroy them. “At 7:15 A.M., Stalin agreed to a directive telling the troops to attack the enemy and destroy him, but even then, hoping against hope, he restricted the order to Soviet territory and admonished the soldiers not to cross the frontier line; still, in other words, he issued no declaration of war or general mobilization orders. Only at noon did the Soviet foreign minister declare war. Soviet forces, the German chief of staff recorded in his diary, were “tactically surprised along the entire front.” Their unreadiness permitted the Germans to win an immense initial advantage, one that cost the Soviet Union uncounted millions of lives over the next four years. http://www.danielpipes.org/2890/appendix-b-stalins-blind-spot
"Pro-Russian separatists on Monday ignored an ultimatum to leave occupied government buildings in eastern Ukraine while another group of rebels attacked a police headquarters as a threatened military offensive by government forces failed to materialize." http://www.cnbc.com/id/101579675
The Ukrainian government is concerned that if it uses force against the Russian militia, it will give Putin an excuse to invade Ukraine. Guess what: if Ukraine does not use force, it will make things much easier for Putin. His provocateurs are doing just fine taking over the Eastern Ukraine.
There has to be a strong response - Ukrainian and strong non-military actions from the rest of the world. Because “Fascism” is not a German word. And Russian Fascism is not any better than German or Italian Fascism.
