US Secretary of War Pete Heggest says the chaotic withdrawal of US forces from Afghanistan was a disaster for the country's reputation and should be investigated seriously and openly.
In part of his comprehensive assessment of the U.S. military's educational institutions, he said this country's war colleges avoid a detailed examination of recent strategic failures, including the U.S. withdrawal from Afghanistan.
Pete Guest also asked why senior US officials failed to predict the collapse of the Afghan government and why the country's operational plans fell apart within days.
