LOL.
Its a serious question, due to me not really researching the difference between nuking a target through bomber transport, and nuking through ICBMs.

And by my comment, im thinking that ICBMs would be immediately picked up upon radar from launch,and the country they are launched on would have time to react to stop them.
While a stealth bomber may be able to get closer to its target and drop its payload simply because of its low Radar signature. And the fact that the country wouldn't know of the payload simply from observation of the aircraft/radar signature.
I may be wrong, but like i said, ive done maybe 2% of research on what im asking.
