Russian President Dmitry Medvedev indicated he would not increase pressure on Iran over its nuclear program in exchange for the United States backing off on plans to deploy missile-defense elements in Eastern Europe. "I don't think any trade-offs are possible in this respect," Medvedev said in a transcript of an interview with the British Broadcasting Corp. aired Sunday. The former US administration said putting the anti-missile system in Europe was necessary to block possible attacks by so-called rogue states such as Iran, but Russia says the system is aimed at undermining its own defenses. "Our position is based on well-known UN resolutions and approaches set forth by the IAEA, namely that Iran's nuclear program should be peaceful," Medvedev said.
