> A separatist candidate who wants Crimea to leave Ukraine and integrate with Russia won more than 70 percent of the vote today in run-off presidential elections, preliminary results showed. His victory sets the stage for a direct confrontation between Ukraine and Crimea, a Black Sea peninsula that is dominated by ethnic Russians.
Russia took Crimea illegally by force, but people of Crimea are hardly victims. Ultimately, the goal of sanctions is to signal that the US is not accepting Crimea as part of Russia. To allow US companies to operate in Crimea would legitimize the annexation. (And as far as the people go - I don't think anyone cares for the people, particularly.)
