Why make such WEAPONS OF MASS DESTRUCTION (WMD) that you cannot use?
Answer in 3 easy steps:
- Build them at insane costs
- Find a war or create a war in which to use them
- Sell it secretly to both sides to increase profits
Bonus round – find hookers, take some drugs, get wasted, blow away all the money and then resign when caught with your pants down.
