I actually think that what Rusia did had to be done by the Ukraine military. After the coup to throw Yanukovich (it seems he was quite a totalitarian thief that has left the country broken but he was democraticaly elected) and the minority taking over the goverment they should had stepped in to force elections and dissolve that rebel parlament that didnt even represent 1/3 of the voters. Thats it if they were honest people who loved their country, their constitution and their democracy.
