External powers always tried to maximize their sphere of influence in other regions. Middle East is not immune from the interference of the external powers. Saudi Arabia is the biggest ally of the US, while Iran and the US are facing the highest level of tensions. US recently sent 1000 troops to the Middle East to counter the threat of Iran. According to Vox “US to send 1,000 more troops to the Middle East to counter Iran”
Apart from US, Russia is present in the region and joined the Iranian block against the US. Therefore, the region is facing uncertainty because of the complex system of alliances and interference of external powers.
Additionally, there are freedom movements such as Palestinian movement and other separatist movements such as Kurdish movements are going on in the region. Therefore the region is observing insurgency, freedom fighting, terrorism and proxies all at once.
