This seems to me to be a very disingenuous comparison and you're not responding to my question. Are you seriously arguing that superior weaponry doesn't help in a war? I think it's reasonably clear that the situation of the Aztecs differs to the conquest of Afghanistan not only by many hundreds of years.

I am not making the statement that all winning a war takes is superior weaponry, as your strawman would suggest. It doesn't take any one factor. Many factors add up. I'm saying this is one of them.
