Ahhh the typical responses to changing the game. 
Why don't you give some examples why it would be bad for the game. As I said the bomb would have to be used on the highlighted base.
It was necessary to use to defeat Japan, so why not be used here, after all it is realism we're after, no?
If that were the case we would have guns randomly jamming, reloads for some vehicles etc. The atomic bomb - even if limited - would still be a cheap way of getting kills, and would ultimately result in people leaving. Imagine, with no limits, 2+ players could level ALL the strats in 1 pass. The only thing it could be used on, where the player would receive the atomic bomb's full potential would be at the strats. But, even then, it's still too powerful.
The Atomic Bomb would be akin to the "noob tube" grenade launcher in Modern Warfare. I don't think the game is currently designed in a way that would utilize the atomic bomb in an effective way anyways, strats would be the only ideal target (and probably the only target HTC would allow to be bombed, for anything else would be overkill).
The system itself would have to be changed.
Respectively,

P.S. If it were to be added, no less than 2500 perks per atomic bomb. No more than 1 bomb per map per side (so 1 AB per side per map rotation). And perks aren't refunded, whether you get to the target or not. At least.. that's how I would do it
