In recent days, Iran and Israel have been engaged in a fierce conflict, attacking each other with drones and missiles.
Israeli Prime Minister Benjamin Netanyahu has stated that the goal of Israel's operation in Iran is to prevent Tehran from creating a nuclear bomb, as well as to overthrow the Ayatollah's regime.
But who could replace the Ayatollah's regime if it were to be overthrown?
According to foreign media, over the past few years we have seen that there is no united opposition that can work together to replace the government.
There are currently various possibilities, including Reza Pahlavi, the exiled son of the former Shah of Iran, who now lives abroad, writes A2 CNN.
He has supporters inside and outside Iran, but we cannot say for sure how many there are.
He also has opponents, including reformists within the country. They may not want to return to the Iranian monarchy that was overthrown nearly 40 years ago.
So, it is not clear whether there is a ready replacement who would take power in the event of the overthrow of the Ayatollah's regime. (A2 Televizion)
