Since the Iranian terrorist attack on two oil facilities in Saudi Arabia on Sep.14, the most repeated question in the region is: "Will this lead to war?! CBS television reported that weapons experts are monitoring GPS systems that were recovered from the Abqaiq and Khurais oilfields in Saudi Arabia after being targeted by drones. CBS explained that GPS systems allow investigators to track the flight of drones and missiles from their target in Saudi Arabia to the airports or platforms from which they were launched. Investigators from the United States, France and the United Nations are analyzing the parts of the weapons used in the terrorist attack. After years of being out of the public eye, former US Secretary of State John Kerry appeared on CBS to say he believed that Iran was behind the attack. British Prime Minister Boris Johnson said he believed that Iran was behind the attack on Saudi Arabia, stressing that he would consider playing a role if asked by the Saudis or the Americans, which means that military action is possible. US Republican Senator Lindsey Graham called on President Donald Trump from the first day to discipline Iran with a military strike, over its sabotage, destabilization and terrorism carried out around the world. There is no doubt that no one wants a war in a region that has been ravaged by conflicts and wars that are still raging in a number of countries. However, Iran is defying the world and testing its patience and trying to lead it to a confrontation of fire and gunpowder, believing that this is the best way to drain the region and the world. Of course, no one wants a war. However, if Iran insists on its evil behavior, provocations, interventions and threats through its agents, then there is no solution but to teach it a lesson that will mark the end of a sinister historical era called the "mullahs regime", which the world has been patient with for more than 40 years. — The author is a Saudi writer.
