I'll say. Reminds me of that old joke about French army rifles - never been fired only dropped once.
From what I gather, the Afghan government forces just tuck tail and run at the first sign of the Taliban. I don't think they ever put up any sort of fight. And in true Arab fashion, the government leaders just bullshit about how they will get it all turned around, any day now.
The whole endeavour was a complete waste of time. I think everybody with any sense knew this, but war is a lucrative business. Most of the trillion dollars spent ends up in the pockets of folks with lots of political influence, so I expect more pointless military actions of this nature to occur in the future. Good ol' crony capitalism at work.
