At the end of a reasonable analysis of the situation in Afghanistan, Robert Kaplan asks the wrong question. It's not a big surprise, as the question he does ask fits nicely into the post-Vietnam perception of American military action. It is, nonetheless, wrong:
To that end, significant numbers of American officers and civilian contractors will be embedded in Afghan government ministries for years to come, helping to run things. But does the home front have the stomach for it?
Ignoring the prejudicial phrasing used ('stomach for it'), the question that Kaplan should have asked was not 'does the home front' but 'should the home front.' Deciding that a multi-year military effort in a failed state far from home is not worth the cost in blood and lives is not an unreasonable one.
