The problem with the whole "Quantity has a Quality" is that - while you may eventually come out on top, you're going to experience horrendous casualties in the process. Maybe when you outnumber the other guy ten to one, and it takes 8 of yours to take out one of theirs, you'll eventually prevail. But you're still taking 8 times the casualties. In this day and age, not many western leaders would accept that.
I think back to WWII - the 50,000+ American Sherman tanks eventually overwhelmed much smaller numbers of German Tiger and Panther tanks due to weight of numbers. But American and British tank crews paid a horrendous price for the relative inferiority in quality of their tanks.
