On August 8, 2014 (July 13, 2014 in the lunar calendar), the US military attacked extremist organizations in Iraq. British media reported on the 8th that the Pentagon said that the U.S. Air Force had launched an air strike against the Islamic State of Iraq and the Levant (ISIS) in northern Iraq that day. The airstrikes targeted artillery positions used by ISIS to attack Kurdish defenders in the northern Iraqi city of Erbil. This is the first military operation in Iraq since U.S. troops withdrew from Iraq in 2011. In addition, the Federal Aviation Administration issued a notice on the 8th saying that due to the "potentially dangerous situation" caused by the armed conflict in Iraq, all U.S. civil aircraft are prohibited from entering Iraq airspace indefinitely. There are a large number of U.S. personnel in Erbil. Pentagon spokesman Rear Admiral John Kolby said that the U.S. military used two F/A-18E fighter jets to drop two 500-pound laser-guided bombs near Erbil, the capital of the Kurdish Autonomous Region in northern Iraq. John Kolby said that the US military operation was to cover the Kurds to defend Irbil, and he also said that there were a large number of US personnel in Erbil. US military airdrops food to civilians besieged by ISIS Since last Sunday, at least 40,000 Iraq people have been besieged by ISIS in the Sinjar Mountains. The serious humanitarian crisis has attracted world attention. On the evening of the 7th Eastern Time, the US military airdropped water, food and other supplies in the area for the first time. U.S. President Obama authorized the U.S. military to launch targeted air strikes at any time to rescue civilians there. Members of both parties in the United States expressed support for this latest strategy towards Iraq. Two Republican senators issued a joint statement saying Obama's decision was good, but not enough. They believe that the United States needs to develop a comprehensive strategy to weaken the armed forces of the Islamic State. After Obama's authorization, the U.S. Central Command mobilized one C-17 and two C-130 transport aircraft that night to deliver a total of 72 bundles of emergency supplies to the Sinjar Mountains. A senior U.S. military official said the emergency supplies, including 5300 gallons of water and more than 8000 quick meals, could meet the short-term survival needs of 8000 people. In addition, two F/A-18S fighter jets escorted the airdrop mission. Obama: The United States will not send ground troops to war. However, Obama emphasized in his televised speech that the United States will not send ground troops, nor will it let the United States fight again in Iraq, and that American combat troops will not return to fight in Iraq. Liu Yueqin, a researcher at the Institute of West Asian and African Studies at the China Academy of Social Sciences, told the Beijing News reporter that the United States does not want to be deeply involved in the domestic situation in Iraq. First, the United States is too busy to take care of itself, and second, the Iraqi government itself is not united enough. Li Guofu, a researcher at the China Institute of International Studies, told the Beijing News reporter that the United States carried out air strikes in Iraq. On the one hand, the interests of Americans were threatened, and the Americans wanted to protect their embassy personnel and experts. The second is the "great purge" that ISIS is about to carry out. Ethnic minorities in Iraq have been hiding in the mountains. The United States is trying to prevent this kind of purge from happening. Li Guofu said that Obama also said that in a situation like Iraq, the United States cannot sit idly by and needs to play a leadership role and work with its allies and the international community to prevent mass killings.
