I listened to some stats about the number of people killed by terrorism throughout the EU last year, and terrorists arrested, and the numbers were miniscule! I know that any terrorism is to be avoided, but all that has happened is that the Taliban has shifted operations over the border into Pakistan, and the Secretary Of State for Defence was on Radio 4 tonight claiming that as a victory!
The notion that you can stop terrorism by military force is farcical - and the re-emergence of the Taliban when the allied troops leave, will repeat history which is what they did when Russia pulled its troops out.
All the Taliban need to do is wait for us to go home, they don't have to go anywhere, they are already home.
To address the Question - it is not possible for our leaders to sound sincere with their sympathies, but that is both the nature of detachment which is required to do what they do, combined with the knowledge that these people have basically died for a futile cause - and that is the biggest tragedy of all.
