For Ukraine and the West, the primary objective should be to ensure adherence to Minsk II — starting with Ukraine’s regaining control over all its borders, which is supposed to happen by the end of the year.

Many senior Russians, including Mr. Putin himself, with financial interests in the West have yet to be sanctioned.
