Will this be the first test of the new administration? From the NYT:

President Dmitri A. Medvedev of Russia greeted his future American counterpart, Senator Barack Obama, with bristling language on Wednesday, promising to place short-range missiles on Russia's western border if Washington proceeded with its planned missile defense system in Eastern Europe....

Mr. Medvedev said that American regulators had inflated a financial bubble and that the ensuing collapse “carried in its downfall to the trajectory of recession all financial markets of the planet.” He also said Washington had started the war in Georgia, saying, “Tskhinvali's tragedy is, among other things, the result of the arrogant course of the U.S. administration, which hates criticism and prefers unilateral decisions.”

But it was the planned missile deployment, a possible early foreign policy test for Mr. Obama, that captured attention in the West on Wednesday.

Mr. Medvedev described specific measures Moscow would take if Washington went ahead with a plan to station a missile defense system in Poland and the Czech Republic. He said Russia would post mobile Iskander missiles — tactical weapons designed for use against targets like long-range artillery and airfields, in addition to missile defense systems — around Kaliningrad, an enclave at Russia's western border. He also said Russia would use radio equipment to jam the Western missile defense system.

“These are forced measures,” he said. “We have told our partners more than once that we want positive cooperation, we want to act together to combat common threats. But they, unfortunately, don't want to listen to us.”
