Sorry to hear about anyone's loss of life.
But how STUPID do you have to get to go to Afghanistan to fight against the American/British military? Technology will win in the end (however long that will be).
This former Gatwick worker was presumably semi-familiar with Western technology - he should have known that the West possesses considerable technological firepower that can HURT people if directed against them.
He made a big mistake and now he is DEAD. The Taliban thinks it can outlast the US/British forces - ridiculous...
Newsflash for them: those who resist will also be DEAD or badly hurt for being mistaken. The Taliban is now condemned - they chose the WRONG side and will now pay for their misdeeds. This former Gatwick worker dug his own grave...
