The Guardian sums up 20 years of military error in Afghanistan in one paragraph

You can read the entire opinion piece, or read just this one paragraph:

For the US, the cost has been high: 2,216 dead and more than $2tn spent. Billions in “aid” are said to have left Afghanistan, much of it to the Dubai property market. The cost to Afghan civilians has been appalling, put at between 50,000 and 100,000 deaths over the two decades, all in retaliation for “hosting” the 9/11 attackers. Is that what we call western values?
