Why haven’t we used our M.O.A.B.?
The “Mother-of-All-Bombs” is a non-nuclear bomb that can destroy entire city blocks. So we don’t need to “precision-guide” it like a drone-delivered “Hellfire” bomb.
“Close Enough” could wipe out the leaders of Isis in their bunkers in Raqqa.
Why not try to win?
Collateral damage is the reason. We fight friendly.
Use gas worked in Iraq under other regimes.
