Iran's former president Mohammad Khatami criticised the government's confrontational foreign policy, saying it plays into the hands of the enemy, in comments reported on Sunday. "Aggressive and sharp slogans play into the enemy's hands to hurt the country and the system," Kargozaran newspaper quoted the reformist Khatami as saying in a speech in western Iran. "Fighting the arrogance (the United States) should not mean increasing the costs of running the country."
