It has been a year, almost to the day, since the revolution in Ukraine overthrew the corrupt, tyrannical, and, in its last days, murderous regime of Viktor Yanukovych. To mark the anniversary of that event, President Petro Poroshenko invited me to the Kiev National Opera to perform my play, Hôtel Europe.
KYIV -- What happens in Ukraine -- not the financial standoff with Greece -- will be the ultimate test of whether European and transatlantic unity endure. The fault lines extending from Ukraine are undermining the fundamental values that have underpinned Europe's postwar peace and prosperity. Failure to defend those values in Ukraine will cause them to unravel far beyond our borders.
