In conventional warfare, you build your weapons, you warehouse them, and if the time comes, you pull them out of storage and you deploy them wherever in the world they are needed. Procurement times are long, but so is the shelf life of something like an F-16--an all-purpose platform that can flies and fights the same way regardless of hemisphere. Cyberwarfare is nothing like this. Generally, a specific threat requires a specific response, and specific cyber targets require specific cyberweapons that may be used once and never used again. As such, cyberweapons can't effectively come off the shelf. They have to be tailor made for the situation, and fast.
