SIR – I am sure all readers share my sadness at the further losses incurred among our troops in Afghanistan. Our first thoughts must be for the families of these brave men.

I recently listened to a debate in the House of Commons and again, find myself questioning the reasons British troops remain in that country. These continual, and increasingly frequent incidents, where allied troops are slain by insurgents wearing the uniform of those we are ‘mentoring’, must cast real doubt on the short-sightedness and false hopes we harbour over Afghanistan.

Since the invasion of Afghanistan, the UK has lost more than 400 personnel. This figure will most likely reach 500 to 600 by the time we withdraw. We know from history that as a withdrawal; of occupying forces approaches, the number of attacks increase.

Despite what our politicians say, there is no doubt in my mind that, as in every other case, Afghanistan will revert to its natural barbaric state within days of US/UK/Nato troops leaving.

I believe the time has come to re-evaluate this mission and take some decisive action, and I join many others who now say, enough is enough!
