Russia's relations with the Western countries are troubled and dangerous in the Ukraine dispute, and an important opportunity may be lost. Russian President Vladimir Putin has recently made a spectacular return to great power politics in the Middle East, at considerable expense to the United States, and now he has humiliated the European Union. The meeting a week ago Friday between Ukraine and the EU may be critical.

It follows Ukraine's unexpected rejection, under Russian duress, of a long-negotiated pre-membership agreement with the European Union.

Ukraine's president, Viktor Yanukovych, unexpectedly rejected the European proposals, as did his supporters in parliament, who voted against resolutions demanded by the EU, including one that would have allowed former President Yulia Tymoshenko to leave prison and go to Germany, officially for medical treatment. Other European demands would have had liberalizing effect on Ukrainian politics.
