[Harmless Teddy Bear]

Atomic bombs are different then nuclear bombs.

But your point is basically correct.

Destroy all life on earth, probably not.

Destroy human civilization, very probable. But we are doing that with no nuclear weapons at all.

[beethovenfan]

Atomic bombs operate by NUCLEAR fission. Hydrogen bombs involve nuclear fusion. Both are “nuclear” in that the atomic nucleus is involved.

Atomic bombs are different then nuclear bombs.

What?

Maybe you mean nuclear weapons are different than thermonuclear weapons.
