Let’s look at it this way... You’re a brilliant person. Say it was like making a bet. Say the over under was 20 million terrorist killed. Would you take the over or the under for a hundred bucks?
Second of all, IF I were a betting person, you could afford that bet; so be thankful; that I don't bet.
Thirdly, there has NEVER been anyone, NOT ANYONE EVER, who has guessed about how many people would die/be killed in ANY war EVER engaged in, in the history of mankind!
You are a child!
