Today's military movements across the Middle East have been recorded as a transition to a new stage in the region's history. The Islamic Revolutionary Guard Corps (IRGC) has officially declared that they have entered into a state of war following the assassination of Supreme Leader Ali Khamenei, who had led their country for many years, in an Israeli attack. This declaration has been accompanied by action, as hundreds of ballistic missiles and unmanned drones launched from within Iran are heading towards Israel and U.S. military bases located in various Arab countries. The situation has created great shock and terror throughout the region. Today's attack is different and of higher intensity than what has been seen before. As the IRGC stated, the military operation named 'Severe Revenge' is aimed at countering and punishing the assassination of Khamenei carried out by Israel. Reports indicate that U.S. bases across Jordan, the United Arab Emirates, Qatar, and Bahrain are coming under heavy missile attack. Iran explained that this is a step taken based on the belief that the U.S. is directly involved in this conflict. The reason regional tension has reached its peak is the recent assassination of Ali Khamenei. This event has shaken not only Iran but the entire alliance known as the 'Axis of Resistance,' and Tehran views this attack as the crossing of a 'red line.' Consequently, the 'shadow war' between Israel and Iran that has remained hidden for years has now turned into an open military conflict. Political analysts have stated that this event is leading the entire Middle East in an unknown direction. The fact that the attacks are on U.S. bases in Gulf countries puts regional stability at great risk. Arab nations seem to be caught between two giant powers. In a statement released by Iran, it warned that any country that allows its territory to be used for an attack by Israel or the U.S. will be viewed as an enemy. In Israel, the Israel Defense Forces (IDF) are on high alert. Although modern defense systems have been deployed to intercept and foil Iranian missiles, the sheer number of launched missiles is proving to be a challenge for the system. Warning sirens are being heard in Israeli cities, and the public is flocking to shelters. Many fear that this situation could be more dangerous than the 1973 Yom Kippur War. On the U.S. side, the White House has stated that it is closely monitoring the situation and that its support for Israel is unwavering. However, the attacks on its bases are pushing Washington to enter a new Middle East war. It is clear that this will create great pressure on the U.S. President's domestic political stability. Due to this conflict, there are also fears that global oil prices could increase by shocking amounts. If the Strait of Hormuz is closed, it will be a major obstacle to the global oil supply. This will have a direct impact on European and Asian countries. Although the international community is making various diplomatic efforts to stop this danger, the sound of missiles is currently louder than the sound of diplomacy. Ultimately, the future of the Middle East will depend on the actions taken in these few hours or days. Iran's move to avenge the death of its leader has put the entire world in fear, and no one knows how far the war might expand. The Middle East region stands on the brink of great destruction.
