THE events in Ukraine have their origin in the final days of the Cold War and the dissolution of the Warsaw Pact.
Then, the Americans gave a promise to Soviet leader, Mikhail Gorbachev, that Nato would not expand east to Russia's borders. This promise was not honoured and Nato drew in 12 former Soviet and Warsaw pact countries.
Further, America carried on the Star Wars programme, which the Russians always felt was directed at them. In effect, the West carried on the Cold War against Russia, and America financed and backed the 2004 Orange revolution to secure an anti-Russia, pro-Nato government in Ukraine.
The Crimea belonged to Russia until 1954 and 60% of its population is Russian.
What Russia has done may be illegal in international law, but as yet, not a single Ukrainian soldier, or civilian, has died.
