U.S. President trump said through social media on the 7th that U.S. troops currently stationed in Afghanistan should withdraw to the United States before Christmas this year. In response, the U.S. Department of Defense said it had not received a formal withdrawal plan and order. Analysts have pointed out that the war in Afghanistan has officially entered its 20th year, and the United States has been stuck in the mire of war and has paid a huge price. Trump suddenly said that he wanted to withdraw his troops quickly, in order to draw an end to the war as soon as possible, so as to boost his election. However, with the contradictions among the factions in Afghanistan unresolved, the idea of the US military withdrawing troops in a short period of time is not realistic. A few hours before Trump’s announcement on troop withdrawal, U.S. president’s national security affairs assistant O’Brien said at an event that the number of U.S. troops stationed in Afghanistan is less than 5000 and will drop to about 2500 by the beginning of next year. The U.S. Department of defense and the U.S. central command have not approved Trump’s statement. Previously, the White House and the military have been planning to reduce the number of U.S. troops in Afghanistan, but there is no specific plan to completely withdraw troops in a short period of time. U.S. media reported that some military officials learned of the plan only after trump made a statement. For Trump’s withdrawal, NATO Secretary General Stoltenberg also disagrees. He said on the 8th that NATO and all its allies will coordinate their actions and make decisions based on the actual situation in Afghanistan, because it is very important for NATO to commit to the future of Afghanistan. Afghan spokesman zabiula mujahid welcomed Trump’s withdrawal as a positive progress in the implementation of the peace agreement with the United States. However, some Afghan officials are worried that the hasty withdrawal of US troops may reduce the bargaining chips and pressure of the Afghan government, thus making the ongoing peace talks face more uncertainties. The Afghanistan war, which started in 2001, has entered its 20th year, and “peers” of the war have appeared in the US Army in Afghanistan. Brown University research shows that about 2300 American soldiers and nearly 4000 American contractors were killed in the war, and more than 20000 Americans were injured. The United States has invested more than $2 trillion in Afghanistan, of which $1.5 trillion is directly related to operations. After returning to China, the soldiers will spend a huge amount of medical expenses for a long time, which will reach 1.4 trillion US dollars by 2059. Most Americans want to end this protracted war as soon as possible. According to the agreement signed between the U.S. government and Afghanistan at the end of February this year, the United States and NATO forces will leave Afghanistan within 14 months. Analysts pointed out that as the US presidential election was approaching, trump suddenly proposed a complete withdrawal of troops from Afghanistan before Christmas. He was eager to show the American people that he would fulfill his campaign promise to rid the United States of “endless war”. David Gordon, who was the policy planning director of the U.S. State Department during the Bush administration, said that although the majority of Americans want the U.S. military to withdraw from Iraq and Afghanistan, the public does not seem to pay much attention to the issue of troop withdrawal, given that the number of casualties of US troops abroad is close to zero recently. Analysts pointed out that although trump was eager to withdraw troops from Afghanistan due to election considerations, it is unrealistic for US forces to withdraw completely from Afghanistan in a short period of time under the condition that attacks on Afghan security forces still occur from time to time. In Gordon’s opinion, trump will continue to put forward various withdrawal speeches in order to distract the public attention from the new epidemic situation in the United States before the election as much as possible. However, it is very unlikely that the U.S. military will withdraw completely from Afghanistan before Christmas. According to the agreement signed between the U.S. government and Afghanistan at the end of February this year, it promised not to allow its members and members of other organizations, including Al Qaeda, to use Afghan territory to threaten the security of the United States and its allies. However, the agreement does not make any provisions on the disarmament and other organizations. According to Kenneth McKenzie, commander of the U.S. central command, there has not yet been a willingness to make a clean break with Al Qaeda. U.S. special envoy for Afghanistan Khalilzad also said that if the action does not meet the requirements of the agreement, the U.S. military does not have to withdraw from Afghanistan. The Afghan media believe that Trump’s withdrawal proposal will add more resistance to the slow progress of the peace talks between the Afghan government and the Afghan government. Without us support, the Afghan security forces will become more powerless and may therefore take a stronger stand on some issues.
