I am watching the EBC News.
The Septic US General in Afghanistan reckons that most ("60 percent") of the Taliban are fighting not for an ideology but for money.
I am not really an expert but might at least some of the Taliban be.... erm..... fighting against foreigners that are.....erm... occupying their country? Or at least that might obviously be one way that they see it?
It doesn't take a great deal of intelligence to realise this.
