Precisely for that reason (among a few others) that I abstained from voting for Mitt Romney in 2012.
Anyway, when now Secretary of State Mike Pompeo was a Representative in Congress: he visited Kiev, and said that it's clear Putin will do his best to try and re-piece together the Soviet Union.
It does not mean that Putin did not act in the best interests of Ethnic Russians within or near the borders of the Russian Federation, or that the US does not have similar interests in the suppression of Islam.
