French presidential candidate Nicolas Sarkozy said Monday that he would not join up with the United States if it decides to carry out a military action against Iran. Sarkozy, the French interior minister and leading conservative candidate in the April-May elections, is seen as the most pro-American of France's presidential hopefuls. He said he approved UN sanctions against Iran over its nuclear program "and has seen that they are working." "The municipal elections were a failure for the Iranian president," Sarkozy told RMC radio. President Mahmoud Ahmadinejad suffered a setback in December's municipal elections. US Defense Secretary Robert Gates has said the United States has no intention of attacking Iran. But Vice President Dick Cheney has warned that "all options" are on the table if Iran continues to defy UN-led efforts to keep Teheran from making nuclear weapons. Iran insists it is only seeking nuclear energy, not arms.
