I agree the top 10 wapons was a little too open ended and hard to narrow down. They should have narrowed the category somehow. And yes I agree that the Discovery channel has gotten simplistic to get to mainstream people that don't like documentaries, but they do have to make money

.
Finally, I do give kudos for correctly identifying the Military industrial complex as the most influential weapon

wcmontour - you slam Mack for not following the definition of weapon so here it is from Mirriam Webster...
Main Entry: 1weap·on
Pronunciation: \ˈwe-pən\
Function: noun
Etymology: Middle English wepen, from Old English wǣpen; akin to Old High German wāffan weapon, Old Norse vāpn
Date: before 12th century
1 : something (as a club, knife, or gun) used to injure, defeat, or destroy
2 : a means of contending against another
So yeah the word weapon did predate the military industrial complex by many thousands of years, yet the word is appropriate. Conventional battles are generally won largely by the ability to get more/better weapons to the battlefield. (ie a means of contending against another or something used to injure)...
WWII was won largely by the US/Russian complex cranking out more material than the Axis could deal with. In some cases the weapons used were even inferior to their German/Japanese counterparts, yet the ability to make them and get them to the front in large numbers made the difference...
Various Nukes/guns/tanks/etc will come and go, but the ability to make "better" and more weapons over the long term is the ultimate weapon.
