US President Donald Trump does not rule out sending American troops to Iran.
"Everything is on the table. Everything," he said during an interview with foreign media.
Trump also reiterated that Iran's new supreme leader "will have to get his approval."
"Whoever succeeds Ayatollah Ali Khamenei will not last long unless he gets our approval. We want to make sure we don't have to go back every 10 years, when you don't have a president like me who won't do that. We are going to elect a good leader, and I would do that," he said.
