The relationship between Iran and Saudi Arabia has been deteriorating for several years now, but has reached crisis point over the first weeks of 2016. Given that both sides are actively participating in proxy wars in Syria, Yemen, and to a lesser extent Iraq, there is a large fear that this ‘Cold War’ between the two countries could turn into something more. But would either country really go to war with the other? Many of the ongoing conflicts in the Middle East revolve around sectarian splits between Shia and Sunni Muslims. While to say these wars are 100% sectarian in nature and completely influenced by international power plays is a gross oversimplification, these sectarian narratives do go some way to explaining the current enmity between the Islamic Republic of Iran and the Kingdom of Saudi Arabia.
