Thanks for that, Andrew. You've just reminded me that Afghanistan is yet another example where, over many, many years, various nations have tried to interfere and control the place, but all have failed.

And it's possibly also worth reminding people that the Taliban emerged from the Mujahadean – those nice anti-Soviets that were fighting the Red Army (example of interference in the country) and were funded, armed and trained by the US, UK etc etc.
