Anti-establishment Max Hastings.
"Mr Cameron is deluded. The tragic truth is that Britain accomplished NOTHING in Afghanistan."

The real "tragedy" is that the militias later known as the Taliban had previously been fostered, funded, and equipped by British and US governments to fight the then Soviet Union in the 1980s. When will they ever learn (- the democratic internationalists, not the Taliban)?

As I wrote before, there does not seem to be much dispute about facts, but about interpretation and consequences for present-day political philosophy. In these fields, historians are not experts at all; they have their opinions and political convictions as ordinary persons.
