yeah i agree with you. firearms had a slow start with the production being slow and the inaccuracy. all i'm just stating is that with discovery of range weapon, the tide of how war was fought changed from melee to a combination of melee/range to mainly just range.
while nukes were originally not as powerful, but with constant development, it turn into one of the deadliest weapon to man atm. The first nuke blast radius was 1 mile, while the nukes these days could probably wipe out tens or even hundreds of miles from half of the world away. I believe that one of the ban for such items was cause it had lasting effects to the human health. As well as if numerous amount were used, it could lead to putting all life on earth underground, since the radiation would cause too much harm.
yes agree with the constant improvement in development, soon nukes wouldn't be as effective or another weapon that is more destructive or efficient would eventually replace it, but it is still being used today as a deterrent.
For economic wars going, everyone knows that without money to fund research development would slow or stall, as well as countries can fall. As for cyber-warfare going on, since it's the information age, learning secrets before they are made known can give an edge, either military or economic. Alot of information are now stored both data files and paper copies(just in case the data files gets wiped), while the first storage method is easier to sort, store, and etc, it also lead data breach being easier, while the latter half is a pain to search through for a specific answer, but has less leakage potential.
