Shack, I came to your point of view a few years ago. I was amazed when Douglas Hurd also reached the same conclusion but many years after he left the Foreign Office.
Wars of necessity or whatever they called WW2 and the Falklands are a waste but a necessary one to preserve our freedoms. Confrontation with Indonesia might have been a war of choice except that we chose to preserve the freedom of our recent colonies.
The modern war of choice however is highly questionable.
What we achieved is manifest. What we hoped to achieve is questionable. What we are going to achieve, who knows.
Whither Pax Britannica now Pax Americana. Why?
