According to the inimitable Steve Bell. In another bygone era (the early 1970s) there was a joke about something that was not very funny. "What do you call 7500 GIs and 10000 US Marines dangling from the runner of a military helicopter?" "An orderly withdrawal from Southeast Asia." (Alternative answer : peace with honor. Honor. What a quaint word.) The same so-called joke can soon be applied to Iraq, but you might want to add "over the smoking wreckage of an overloaded British helicopter?" And they had the gall to say Iraq was no Vietnam.
