SEOUL, SOUTH KOREA - In a private conversation made public by a hot microphone, President Obama appeared to be putting off diplomatic talks with Russian leaders about a controversial missile defense system until after the November election -- prompting quick attacks from the president's Republican rivals.
The conversation was caught by television footage of a casual one-on-one chat Monday between Obama and Russian President Dmitry Medvedev. On the tape, Obama leans toward Medvedev and can be heard giving him a message for the once-and-future Russian president, Vladimir Putin.
"On all these issues, but particularly missile defense, this can be solved," Obama said. "But it's important for him to give me space.
"This is my last election," Obama went on. "After my election, I have more flexibility."
"I understand," Medvedev responded. "I will transmit this information to Vladimir."
The exchange raised alarm among Obama's critics about his long-term commitment to the missile defense system. The United States has promoted it as a shield to protect Europe from missile attacks by Iran. The Russians fear it would be aimed at them, and opposition to the missile shield was a major theme of Putin's recent presidential campaign.
Putin, who previously served two four-year terms as president, won a new six-year term March 5 in an election that critics charge was flawed. He will succeed Medvedev, who replaced him in 2008 when term limits prevented Putin from seeking a third successive term.
Mitt Romney, the Republican front-runner, accused Obama of "pulling his punches with the American people" and obscuring his plans for the missile defense system.
