US President Barack Obama is considering a dramatic change in strategy with regard to the Iranian nuclear program, according to officials quoted by the New York Times on Tuesday. The shift in policy, according to the report, centers on the US dropping its insistence that the Islamic republic immediately cease all activity in its nuclear program during the initial phases of talks. The US would instead encourage Teheran to allow inspectors to visit its nuclear facilities. The aides quoted in the New York Times report said that Obama was still deciding exact details of the plan. "We have all agreed that is simply not going to work - experience tells us the Iranians are not going to buy it," a senior European official involved in the talks with the US was quoted as saying. "So we are going to start with some interim steps, to build a little trust."
