Explanation:
The Middle East is a region that has been having a lot of problems, especially in the last century and continuing in the present. There have been multiple factors that have led to this, varying from politics, religion, resources, the formation of new states, the terrorist organizations, etc.
The first major problems ocurred after the partitioning of the region, where the countries that ruled over it set borders in accordance with their views and interests. This led to a lot of disputes over territory, but also multiple ethnic groups being left without their own country.
After that, the granting of Israel to the Jews by the international community led to huge tensions. Several wars were waged between Israel and several Arab countries, where the new and small country managed to sustain the attacks and win each of those wars. The tensions are still present though and always on the verge of escalation.
The war in Iraq, in the early 2000s, happened because of allegations of using biochemical weapons, genocide, dictatorship, and terrorist organization layers. It led to the total destabilization of Iraq, but also led to larger-scale destabilization later on in the region.
Because the majority of the leaders in the Middle East are dictators, with people living in fear and being very restricted, decided to rebel. This led to mass rebellions against the governments in numerous countries, some of which were successful, while some not some much.
