Is there a possible comparison with "the Afghan business" in the "confrontation" with Indonesia from 1962- 66 ? Coming after (and sometimes considered as) an extension of the post-WW2 Malayan Emergency, you could say though that it also took a great deal more time to reach a modus vivendi along the Malaccan Strait and the Borneo border.
But this was another far-away country of which much of Whitehall knew nothing, and most of the then meeja quietly ignored.
Of course, the Viet Nam business was "where it was at" (awful phrase, but succinct) and the result was two prosperous, more-or-less "democratic" countries, with the "Communist threat" removed, after which the British, Australian and New Zealand forces could retire with honour and nomal diplomatic relations quietly resume in the area.
