ANKARA (Reuters) - Iran's success in winning an end to international sanctions will only intensify a power struggle among the faction-ridden elite, and President Hassan Rouhani cannot count on domestic political support from the supreme leader before two critical elections.

However, Tehran's leadership has now decided on a less confrontational foreign policy than in the past, although a restoration of full ties with the "Great Satan" - the United States - remains out of the question, officials say.
