Russian President Dmitry Medvedev told ABC's George Stephanopoulos that President Obama is a "thinker" unlike "other people." The Russian president seemed to be referring to President George W. Bush.

"I won't name anyone by name," he said.

In a rambling fashion, Medvedev also talks in vague terms about an "agreement" reached between President Barack Obama and his own country over reducing the number of active missiles in their respective arsenals.

"We agreed upon and we spoke about with President Obama and talked about with American representatives that we should cooperate in the creation of global missile defense systems," he added. "But if that process will go eventually on such a scenario which, according to our impression, will lead to the quantity changes, then such a question could be posed by our side. And this is the principle of that reasoning, and understanding as well about that oral statement yesterday."

The creation of a US missile shield in Europe, aimed at deflecting a threat from a nuclear-armed Iran and potentially from Russia itself, has been a sore point between Russia and the United States.
