Down the great dragon was hurled... Satan... having great anger Rev.12:7

War broke out in heaven (1914), Satan was hurled down to the earth having great anger knowing he has a short period of time". "The dragon gave to the wild beast it's great power and authority, ... and they worshiped the wild beast... and the dragon" Rev.13:1-4.
Why would Satan (the "ruler of the world") Jo.14:30, give his authority to the global military industrial complex? Is the "complex", with it's 30,000 nuclear weapons, satan's designer doomsday device (misery loves company)?. How can we defend? See the slide show at [link to www.dgnglobal.com]
