Looks to me like Yushchenko and Co are trying to create something else to stir up the people in a fake emergency and back him even as he looses power in Kiev.
Sounds to me more like the Ukranians are happy to see ships crash into rocks in order to extort cash from Russia.
The breaching of the contract and the endangerment of both military and commercial shipping in the Black Sea by Ukraine is a reprehensible act. If the Ukrainians are upset about energy, they still have no right to endanger the safety of ships just to make a point in a very immature manner.
