However, it is estimated that a number of European countries are concerned about the speed of the withdrawal and its impact. The U.S. ambassador to Afghanistan warned that a peace deal could risk the Taliban regaining power, much like after the 1973 Paris Peace Agreement, which defeated the U.S.-backed South Vietnamese government in the case of Saigon.   Pakistan has warned that rising tensions in the Gulf region following the assassination of Iranian General Qasem Soleimani could affect the already delayed US-Afghanistan peace process.  2) Withdrawal of US troops: The US agreed to the “withdrawal of all foreign forces from Afghanistan” and said that US personnel would be reduced from about 13,000 to 8,600 in the first 135 days. “The commitment and action in support of the Taliban`s `commitments` aims to withdraw all remaining forces by the end of April 2021. After months of talks in Doha, the capital of Qatar, the deal enters negotiations that have been encouraged by the United States. In Afghanistan, the two sides are still at war and Taliban attacks on government forces continue unabated. The Afghan peace process includes proposals and negotiations to end the ongoing war in Afghanistan. Although sporadic efforts have taken place since the war began in 2001, negotiations and the peace movement intensified in 2018, amid talks between the Taliban, the main insurgent group fighting the Afghan government and U.S. troops; and the United States, thousands of whose troops are present in the country to support the Afghan government.
