What Middle Eastern country holds animosity?

Many Middle Eastern countries experience varying degrees of animosity towards one another, often rooted in historical, political, or sectarian conflicts. For example, Iran and Saudi Arabia have a longstanding rivalry, driven by differences in political ideology, sectarian divides (Shia vs. Sunni), and competition for regional influence. This animosity is often reflected in proxy conflicts throughout the region, impacting relationships between other nations as well. Other notable tensions exist, such as between Israel and several Arab nations, particularly concerning the Palestinian issue.
