Sandman:
A thousand dead, terrible wounds; the Union Jack flying again over the Falklands (pop. 1,800); rejoicing and mutual congratulation in the House of Commons; champagne and Rule Britannia in Downing Street - each must draw his or her own balance sheet and historians must decide where to place the Falklands War in the annals of Britain's post-1945 adjustment to her reduced circumstances as a declining power.

Truth is one of the first casualties of peace and, now that it has broken out, we had better be on our guard against disinformation. President Harding was right, although his vocabulary wasn't, when he announced the return to "normalcy".

Things will never be quite the same after Mrs Thatcher's war, but they will be more the same than is apparent on the VF Day.

The Falklands themselves, the prize of the war, will quite quickly retreat down the league table of public concern. For a while they will remain too serious a matter to be left to Sir Bernard Braine but before very long, I would guess, they will revert to their traditional place in British politics, one they have occupied since they were brought briefly to Dr Johnson's attention, that is - out of sight and out of mind.

So, it appears that you believe that countries should not protect themselves/their dependencies against foreign invasion?
Does this mean we should let Russia roll into and over Ukraine?

If that is not what you mean, then Margaret Thatcher's defence of the Falklands was probably correct.
"Mrs Thatcher's war"? You may have missed that it started with an invasion by Argentina!
