The Pentagon is reportedly floating a new plan that would see all U.S. troops withdrawn from Afghanistan within the next three to five years, The New York Times reported Thursday.

The plan is reportedly being offered in peace negotiations that could result in the government in Kabul sharing power with the Taliban, according to the report.

Officials are discussing the plan with European allies, the Times reported, and would cut the roughly 14,000 U.S. troops in Afghanistan by half within the next few months. Under the plan, the 8,600 European and Australian troops stationed in the country would be tasked with training Afghan troops, shifting U.S. forces' focus to counterterrorism operations, according to the Times.

A Pentagon spokesman, Lt. Col. Koné Faulkner, told the Times that no plans have been finalized yet, and that the Trump administration is "considering all options of force numbers and disposition" in Afghanistan.

High-level negotiations began between U.S. officials and Taliban negotiators at the group's political office in Qatar on Monday, according to the Times. Among the participants was included Gen. Austin S. Miller, commander of coalition forces in Afghanistan.

The talks represent the highest-level negotiations so far between U.S. and Taliban officials as the Trump administration seeks to end America's longest-running armed conflict.

Afghanistan's government, currently led by President Ashraf Ghani, has reportedly not been involved in the ongoing negotiations due to Taliban skepticism of his government, according to the Times.
