Over the course of the last week, Russia has celebrated the second anniversary of its war with Georgia in typical style: A visit by President Dmitry Medvedev to the breakaway province of Abkhazia, which Russia now recognizes as an independent country, and the announcement by a Russian general that the air force had stationed in Abkhazia the S-300, a highly sophisticated anti-aircraft system, to counter unspecified Georgian threats. While the Georgians, who tend to treat each new act of Russian provocation as a prelude to apocalypse, reacted with alarm, a State Department spokesman waved off the S-300 as old news. President Barack Obama's administration has tried -- successfully, so far -- to strike a balance between defending Georgia and preserving the "reset" with Russia. But what will it do if Russia simply refuses to withdraw from territories seized in an illegal and unjust war?
