<< Yeah, that's what happened. >>
It is.
Congratulations.
You're Right on the average.
One Right out of ten is about average for "you lot."
[Another clue: (The Pearl Harbor/Hilo analogy having flown over your head) When Hitler headed for Prague, that era's Limeys didn't respond by invading Czechoslovakia!]
So, the fact seems to have escaped you that the Argentine Army was comprehensively routed in what is universely recognised as a stunning military achievment, overrunning enemy positions that were prepared and dug in, in harsh conditions and terrain, at the end of an 8000 mile long supply line, and the regime that sanctioned the invasion was overthrown a short while later.
Apparantly, by your logic, that makes the Argentines 'all-powerful' and constitutes a total humiliation for the British.
No, we didn't have the resources to invade the Argentine mainland, not that it was either necesary or politically desirable. You also overlook the fact that Thatcher did this in the face of less than 100% American support and had to give Reagan a lesson on what was at stake in the face of his attempt to broker a ceasefire to save face for the Argentines.
At least try to get some factual basis into your obvious anti-British trolling.
