Answer:
U.S. withdrawal from Afganistan
Explanation:
The recent withdrawal from Afganistan came very, very quickly after 20 years of U.S. presence in the country. After withdrawal, Kabul fell to the Taliban in under a week and the Taliban control almost all of the country and are gaining iternational recognition as the de facto rulers.
In Viet Nam, the United States made a similar quick exit after 10 years of fighting. However, the U.S. departure of Viet Nam was a military defeat - the withdrawal from Afganistan was in recognition that U.S. military involvement was no longer successful in the country and the Taliban could not be eliminated or the cost of eliminating the Taliban would be so great and with so little benefit.
In Viet Nam, the U.S. was effectivley defeated by the North Vietnamese and the country was reunified under the North. The high cost of human life and U.S. tax dollars for what amounted to only a postponement of the fall of a economically insignificant (Viet Nam did not make significant strides until after the war to become a major textile manufacturing center) country that posed no real military threat to the U.S. or allies is the commonailty between the two conflicts, regardless of the technical distinctions behind why the U.S. left.
