The tendency of human beings is to be inert and not to do anything. You can't make them do something unless they really want to do it. If the United States has established, funded, and is personally supervising grassroots networks (through C.I.A. agents or other officials) to create protest or an illusion of protest, I'll acknowledge your claim. But making a handful of inflammatory remarks and leaking information about high up political wheeling and dealing doesn't pass muster. That's throwing a few matches into an oil drum that is already burning.
More importantly, the line between who wants to be part of the Russian Federation and who wants to be part of the European Union is drawn mostly between ethnic Russians and ethnic Ukrainians, who make up about 17% and 78% of the population respectively. But just as the political leadership in Washington is disconnected from the voice of the common man, the leadership in Kiev tends to follow its own establishment logic. Namely, that Russia is the regional power, not Europe, and that deference must be given for Ukraine to be safe (and for the political leadership to remain rich with Russian economic and political connections).
In conventional elections, it would take decades or hundreds of years to bring the leadership into line with what the people want.
