(New York, December 9, 2015) - Today, TIME names German Chancellor Angela Merkel TIME Person of the Year.TIME Editor Nancy Gibbs writes: "Not once or twice but three times there has been reason to wonder this year whether Europe could continue to exist, not culturally or geographically but as a historic experiment in ambitious statecraft. Merkel had already emerged as the indispensable player in managing Europe's serial debt crises; she also led the West's response to Vladimir Putin's creeping theft of Ukraine. But now the prospect of Greek bankruptcy threatened the very existence of the euro zone. The migrant and refugee crisis challenged the principle of open borders. And finally, the carnage in Paris revived the reflex to slam doors, build walls and trust no one. Each time Merkel stepped in. Germany would bail Greece out, on her strict terms. It would welcome refugees as casualties of radical Islamist savagery, not carriers of it. And it would deploy troops abroad in the fight against ISIS…. You can agree with her or not, but she is not taking the easy road. Leaders are tested only when people don't want to follow. For asking more of her country than most politicians would dare, for standing firm against tyranny as well as expedience and for providing steadfast moral leadership in a world where it is in short supply, Angela Merkel is TIME's Person of the Year."
