Doesn’t the ground just absorb about half of the energy? (And become nasty fallout)
Fat Man was tiny by later standards. The B41, which was actually deployed, was three orders of magnitude more powerful. Sizes have come down again since delivery got really accurate, but the workhorse B61 can be dialed to somewhere from 10 to 20 times Fat Man’s yield.

It absorbs a lot, and it channels a lot of the blast up.
Yes, but also its not easy to smuggle a large bomb either.
