That's a huge leap you have made there. Comparisons between the early stages of the Barbarossa campaign and the Falklands war are really really hard to come by, I mean by the standards of even one day in Russia in 1941 (post June 22nd), the Falklands Conflict, (which is how we mainly refer to it in the UK anyway) doesn't really justify being called a war.
Yes the Argentines were badly led, though they did fight well on occasions. Often soldiers fight more for their mates than for their leaders, and they fight to stay alive.
As for Russia, well it's just too big a war to simplify like that.
I wasn't saying the Argentines were badly led or that they didn't fight well, but GI Juan, the average soldier and often a conscript had a bad morale and little will to fight...
From the book, I remembered reading in the 1980's about this war, is that the Falkland war show the difference between a conscript and a professionnal army, and between a motivated and a non motivated army...
