Diplomatic tensions in the Middle East are a complex and layered issue, involving various states and non-state actors. In recent years, the region has become a stage for conflict, shifting alliances and threats that impact global stability. One of the focal points of tension is the conflict between Iran and Saudi Arabia. The struggle for influence between the two countries, based on differences in Sunni and Shia ideologies, has led to proxy wars in Yemen, Syria and Iraq. Saudi Arabia supports the Yemeni government in its war against the Iran-backed Houthis, while Iran serves as the main sponsor of the group, as well as other powers in Syria and Iraq. These tensions culminated in rocket and drone attacks carried out by militant groups, which created a tremendous impact on global oil prices. On the other hand, the Israeli-Palestinian conflict remains a constant source of tension. With recent events such as the recognition of Jerusalem as the capital of Israel by several countries, such as the United States in 2017, the situation has become more complicated. Protests and clashes occur frequently in the West Bank and Gaza, exacerbating an existing humanitarian crisis. The varied international approaches, from Israel’s normalization agreements with Arab countries to UN resolution efforts, demonstrate the complexity of diplomacy in the region. Amidst all this tension, the latest developments in relations between Qatar and the Gulf countries are also attracting attention. After years of isolation, Qatar has begun to ease tensions with Saudi Arabia, the United Arab Emirates and Bahrain. This dialogue is considered important for creating stability in the region and shows how quickly the situation can change in the Middle East. The involvement of the United States and Russia in Middle Eastern affairs also creates different dynamics. The US, with a foreign policy that tends to support Israel and its allies, and Russia which shows support for the Bashar al-Assad regime in Syria, created a shift in power that also affected diplomacy. However, the presence of non-state actors such as extremist groups and militants increasingly makes the situation complicated and uncontrolled. The climate crisis, demographic shifts and population growth in Arab countries could also exacerbate diplomatic tensions. Social and economic dissatisfaction may encourage further protests and instability, with countries with limited resources possibly experiencing greater unrest. Further analysis needs to be carried out to understand how all these factors interact with each other and their influence on the foreign policies of major countries. Concerns about arms proliferation and terrorism also continue to be a major concern in the region. The ongoing tensions in the Middle East are a reminder that diplomacy requires a careful and highly strategic approach to prevent greater conflict in the future.
