In a landmark prisoner swap deal between Israel and Iran, over 400 prisoners were exchanged for six billion US dollars in cash, and the deal has highlighted the role of money in Middle East politics. The deal was prompted by recent attacks from Hamas directed at Israel, and signals a growing confidence between Iran and Israel in working together to reach a peaceful solution. Furthermore, the US dollar has been caught in the spotlight due to the large amount of money being transferred despite current relations between these countries.
