Hmm, why do you think the US should pay for Ukraine? What would that achieve, besides lost money?
I would partially disagree
I don't think the Right Sector or other neo-nazi would be acceptable by anybody, they would pose serious threat for all neighbor countries.
I would agree that changing government is a goal. There is no need to set pro-Russian government, reasonable government would be enough to work with. Right now Ukraine does not have reasonable government, at least judging by the budget and goals current Ukrainian government is anti-Ukrainian
PS: Soros obviously does not want to lose money, so he would come with any propaganda to prevent the default.
