Blitzkrieg is like "a war being done quick" or "a war which wont last long and to be ended quick". I think the key is the understanding of "Blitz", which is associated with things like "fast" "hitting hard" "dangerous" "powerfull" "in a short amount of time" "to release a high amount of energy in a short amount of time" (and so on).
