Robert Kagan writes for the Washington Post on the situation in Georgia:
"Putin's aggression against Georgia should not be traced only to its NATO aspirations or his pique at Kosovo's independence. It is primarily a response to the "color revolutions" in Ukraine and Georgia in 2003 and 2004, when pro-Western governments replaced pro-Russian ones. What the West celebrated as a flowering of democracy the autocratic Putin saw as geopolitical and ideological encirclement.
Ever since, Putin has been determined to stop and, if possible, reverse the pro-Western trend on his borders. He seeks not only to prevent Georgia and Ukraine from joining NATO but also to bring them under Russian control. Beyond that, he seeks to carve out a zone of influence within NATO, with a lesser security status for countries along Russia's strategic flanks. That is the primary motive behind Moscow's opposition to U.S. missile defense programs in Poland and the Czech Republic.
His war against Georgia is part of this grand strategy. Putin cares no more about a few thousand South Ossetians than he does about Kosovo's Serbs. Claims of pan-Slavic sympathy are pretexts designed to fan Russian great-power nationalism at home and to expand Russia's power abroad."
