I think this covers it well,

Since none of our politicians will listen to public opinion, the time has come for some kind of mass demonstration or civil protests, such as the American people took over Vietnam, that brought that useless war to an end.
Let's not be fobbed off with further excuses why we are there.
First it was to seek out that mystical figure Usama bin Laden.
Then, to destroy the Poppy fields to stop the end product of drugs making there way onto the streets of Britain.
Then to destroy the terrorist training camps.
Then to build hearts and minds thus helping the Afghan people rebuild their country, and provide them with a dam and schools,
Then we were there to help train the Afghan Army so that they could in time take over from us.
Then it was to prevent terrorist attacks on mainland Britain.
I think the latest is to make sure that their election is carried out as peacefully as possible.
We have heard it all from our politicians of all parties, and the wasteful killing and maiming of young lives go on and on, 50, 100, 150, 200, how long before the next mile stone is reached.
The bottom line is that we cannot pull out, while we are still subservient to the US. If the rest of NATO can make their own decisions on troop deployments why can't we?
I say pull out now, use our troops for the purpose they are employed i.e. the defence of the mother country, and then I say to the Taliban come on over, we are ready for you.
