Betray what? did you know that America has spent more than 2 trillion dollars on this useless war? when America decided to leave Afghanistan it was the wisest decision they could make. America has betrayed no one here. From the beginning, America was involved in Afghanistan to take their revenge on al-Qaida. This caused security chaos in Afghanistan and America helped Afghanistan to solve this problem. But after nearly 20 years of a meaningless war, Afghanistan has not changed, so America left Afghanistan, especially after the Taliban declared they were ready to run this country, America was determined to leave this country. So America doesn't betray anyone here.
