The prospect of higher energy prices should not stop the world from imposing sanctions against oil-rich Iran, US senators said Sunday. Sen. John McCain, an Arizona Republican, said sanctions will be tough but that Iran poses a greater danger to the United States than Iraq at this point and must be contained. "If the price of oil has to go up, then that's a consequence we would have to suffer," McCain said on "Face the Nation" on CBS television. Iran restarted its research at a nuclear facility last week after a two-year freeze. The Bush administration says Iran wants to make nuclear arms and is pursuing harsh penalties through the United Nations Security Council.
