mentality of interventionism without a plan summed up right there.
I'm not even in the "Buhuh, bad yanks just wanting war to enrich themselves" boat but surely you realize how stupid it is to blame the Afghan society after walzing in, creating a vacuum and then have no idea how to proceed except for "let's build a couple of buildings".
There was no vaccum created since there was nothing there before the US arrived beyond a fractured country with the Taliban (with the help of Al-Qaeda) running the southern and eastern parts, and the Northern Alliance controlling the rest. Once the Taliban were expelled within days, the ISAF and later NATO troops did the right thing and attempted to get an Afghan government set up so that Afghans could have a democratic process. That process has now after 20 years apparently failed.
