First off it has far from been established that it is "foreign" troops. And how can it be "foreign troops" when 90% of the population is Russian?
Secondly the regional government is actually pro-Russian and according to the reports, the men with guns who took over the buildings, did so to protect them from troops and armed men from Kiev.
The whole situation is driven by fear and that fear is based on past history. The people in Crimea dont trust Kiev because Kiev has removed and tried to remove even more rights form the area. It use to be very independent from the rest of the Ukraine but Kiev has been for years been pulling back powers. And that has all to do with one thing... the military port of Sevastepol... presently under Russian control and wanted badly by the Ukrainian nationalists. That is what Russia is protecting.
No and no. Russia has admitted it moved some troops to the Crimea yes, but it has not said that those troops have taken over the government buildings or anything else.
Also the so called analysts are just that.. analysts and often with a hidden agenda, especially the American and British ones.
Some are even pushing for war for **** sake..
