NATO and Russia have had a rocky relationship ever since the country's invasion of Georgia last summer. Now, any pretenses of cordiality have been thrown out the window as the military alliance has expelled two senior Russian diplomats accused of spying. Russia reacted angrily, saying the charges were "invented, irresponsible, and provocative." The expulsion of the two men has led to a war of words, as President Dmitry Medvedev denounced NATO's plan to hold military exercises in Georgia using fiery language. NATO returned the favor by criticizing Russia's dominance over the separatist territories in Georgia. The row has severely damaged relations between NATO and Russia in the lead-up to their major meeting next month.
