Then I can’t see it happening, unless it’s part of a global free for all, a pig pile on the USA and Britain. Taiwan, Iran/Hormuz at the same time, would greatly over stretch us. That’s when the second tier enemies would jump into the fray.
Seems I read some books about this kind of scenario......
It just means all the more that they will need our direct military help (and not just logistics).
If we do not provide that help, then the UK, IMHO, in either case, would not be able to get past Venesuela on the way down to the Falklands.
Such a scenario as this could be one that was used to distract us, along with others. And, in fact, Venezuela and Argentina in those books did form the nucleus for the South American contingent of the belligerents we faced in the series.
