There are two things I suppose everyone would agree are true about the remarkable events of the past several weeks in Afghanistan.

One is that we are witnessing the latest  major loss in a string of wars and "incursions" that the US has lost since the end of World War II. The other is that the entire  two-decade-long, $2.3-trillion US invasion, war and occupation of  one of the poorest countries in the world, was an abject failure from the beginning.

Officially, the US invaded Afghanistan because its ruling Taliban government had allegedly permitted Al Qaeda, a shadowy jihadist fighting organization founded by the Saudi Osama Bin Laden (with CIA assistance), to establish several training camps there where he purportedly plotted the 9-11 attacks on the World Trade Center, the Pentagon and perhaps the Capitol building or White House.
