So you did. Well that seems to settle it in our favour.

They are obligated to stay. When they agreed to send troops to Iraq, they knew if it was going bad, like now, that they could not just get up and run with their tail between their legs or the whole country would go to hell. Thank God they aren't like Spain and didn't leave after getting attacked. I really admire GB, a realible ally.
It is of course possible we would have served you better by trying to stop you doing the whole silly thing from the start, but I expect you are right we will stick it out to the end now.
