Bring all our boys home from everything except our normal bases overseas.
We've done what we can to "free them from tyranny", but theres no thanks.
Leave them to their own devices, let them get on with it. If they want to kill each other thats fine.
We are not the appointed World Police. OK we had lots of influence in the world back in the days of thr British Empire.
Those days have gone - we are a small island on the west of europe who can hold our own in a fight thanks. That should be enough - we do not need to take on the rest of the worlds problems as well.
Even if its simply that we can't afford it.
You don't see other "Superpowers" i.e. Russia, China,Japan, intervening in places, or even offering to help in Afghanistan, Libya, Iraq,Iran, Middle East, Korea....
Bring our boys and girls back. they have done more than enough, and many have died without justification.
They are first class people, and I'd rather they be here than in the middle of somewhere inhospitable.
They could supplement Law and Order here for example, especially during the olympics. Who bets there will be a serious terrorist threat in July after what we,ve got involved with in World conflicts?
I certainly would not be surprised, particularly with our very ethnic populous in and around london.
