Halfway through Joseph Heller's magnificent anti-war novel Catch-22, the old Italian man in the comfort house uses the eponymously-named logic to argue that Italy is doing better in the war than America because as Italy has already been occupied, Italians are no longer being killed. Moreover, America probably won't last as long as frogs, who have been around for millions of years.
His hapless debating opponent, Captain Nately, is reduced to arguing in favour of America's international supremacy and the values it represents.
But his faltering patriotism and idealism fall on deaf ears.
This unforgettable exchange has often haunted me, possibly because of my dual heritage. I've grown used to incessant jibes about Italians allegedly being cowards, and the racial insult WOP apocryphally standing for Prisoner Of War backwards.
No matter that it's incorrect and the etymology is actually southern Italian dialect: from guappo meaning swagger (since you ask).
The old Italian came to mind over the weekend as Britain's Foreign Secretary William Hague became the latest politician to argue defensively that Britain's role in the world has not been diminished by last week's parliamentary vote over Syria.
Hague's well-meaning defence presupposes that our standing in the world continues to be defined by Britain's ability to act as a global policeman.
It touches upon Britons' preferred definition of themselves as a global military power alongside America, Russia and China and — arguably — the French.
William Hague also acknowledged that there was a great deal of unease about intervention in Syria among the British public in the wake of the Iraq war. And in that regard, the Commons did its job. In rejecting the Prime Minister's wishes, it was reflecting the majority opinion of the people.
When I talk to so many foreigners about what they admire about Britain and they usually do admire Britain — it is never because of the country's military might.
Conversely, they often have a more positive view of our democratic process than we do. It is exactly because we put such matters to the vote and adhere to the outcome that they do admire us. It's a tricky thing, democracy. It doesn't always go the way our leaders want it to, both at home or overseas — look at Egypt.
Even trickier is Britain's quest to find peace with itself as a 21st Century middle-ranked power. The Italians, since Mussolini, have no greater global aspirations, preferring to focus on their culture, history, flair and other attributes.
The Dutch, Spanish and Portuguese have long since come to terms with lost power. Britons still cling on. They need to let go, and stop apologising for its loss. Britons should be proud of who they are, not keep harking back to who they once were.
