The international reaction to the Russo-Georgian War covered many nations, non-governmental organisations and non-state actors. The conflict began in August 2008 in South Ossetia but spread elsewhere in Georgia. The war had a considerable humanitarian impact and affected the financial markets of Russia and Georgia. In general, Georgia accused Russia of aggression, whereas Russia accused Georgia of genocide and crimes against humanity targeting Ossetians and Russian peacekeepers. Most other countries called for peace, with some demanding respect of Georgia's territorial integrity while others supported Russian intervention. The Russian invasion of its US-aligned neighbor caused Russia–United States relations to plummet for the first time since the end of the Cold War and led to heated verbal exchanges. In the next year, the new US administration chose a policy of the reset.
