"Google and ye shall receive.... It's really not tough to find this stuff out, even if it hasn't made it onto the 9 o'clock news."
er yes, thanks for that, I was trying to be polite and simultaneously bump the thread 
still doesn't answer the question:
"why are the UK forces involved". we have both "obvious" and "political " reasons NOT to be involved, like all those you have mentioned - yet there we are, very likely to bring in the ground forces next
it seems ridiculous - we have no money, depleted services, you name it, there is no good reason to be there. I just don't get it, even though I grasped IRAQ & AFGHANISTAN (though didn't like it)
So, go on then - what are the obvious & political & other reasons WHY we are involved do people reckon?
