Russian President Dmitry Medvedev has accused the West of breaking promises made after the fall of the Iron Curtain, saying that NATO's expansion into Eastern Europe violated commitments made during the negotiations over German reunification.

Newly discovered documents from Western archives support the Russian position.

Of course there was a promise not to expand NATO "as much as a thumb's width further to the East," Mikhail Gorbachev, the Soviet president at the time, says in Moscow today.
