So, an 8000 mile supply line, an amphibious landing and forced march (Yomp or Tab) over freezing, wet and inhospitable terrain. Then to fight a dug-in, prepared enemy who controls the high ground and, in a lot of instances, out numbers you. And win.
Well Im fairly impressed!
Without command and control SNAFUS on the Argie part, the Brits would have been much more roughly handled. Perhaps they still would have won. But without heavy (make that MASSIVE) US help and Argentine General Staff incompetence, it would have been a good deal uglier than the mess it truly was.
LESSON HERE: You cannot win a war with Lyndon B. Johnson/McNamara-style command and control
