@Touken,
No, the right sector is obviously not the solution (and in my opinion can never be...). Some western politicians should realise that and stop their support of the coup-appointed governement. All those people in Eastern-Ukraine will not give up until there is a change in the current interim-governement, restore of their rights and release of the captive activists. Sending tanks and thousands of soldiers will not make them change their minds on the contrary it might act as the last straw for russia to start acting militarily which might be a benefit for the anti-kiev protesters but it will also trigger a reaction from nato and probably America... At least economical sanctions first, later most likely military intervention. And that's when **** will really hit the fan, such a scenario must be prevented at all costs.
Unfortunately as things are evolving right now I don't think there will be a peacefull 'ending'.
Ofcourse things are more complicated than what I summarized but this shortly displays my point of view.
