A power vacuum in the region has been emerged since the withdrawal of the American presence and due to the contributions of Arab upheavals. The clashes and the disputes in the region is the direct result of this vacancy. The attack on the Saudi Embassy by en masse in Iran was an indicator of the hatred after the execution of Shiite religious figure Nimr al-Nimr who was alleged to have sided with the terrorists in Saudi Arabia. The last example of the conflict between the sides testify the general understanding that the threat to world peace emerging from the Middle East does not only arise from terrorism but also from the danger of Sectarian clash between Muslims which began even earlier than the Arab Spring. Although the roots of the conflict dates back to the Iranian Revolution of 1979, the rising influence of Tehran may be dated back to the overthrownment of Saddam Hussein and the withdrawal of Israel from Lebanon. Starting from Iraq, in 2003, US-led coalition ousted a Sunni-Arab counterweight to Shia-Iran and the geopolitics (It gained importance resulting from the territory under the control of weak states that invites the foreign intervention) of the region had mostly been shaped by Iran since then. The contributions of the withdrawal of the USA from the region and the Arab Spring for the destruction of the existing stability prepared a new power vacuum, which was also filled by Iran.
