Tactical nuclear weapons are on the table in preventing Iran from weaponizing their nuclear program.
That would certainly send a message, but open the door for a world of hurt. To date, mutually assured destruction has always been the deterrent against the use of nukes.
While I understand the physics behind nuclear weapons and the idea that a tactical bunker-busting nuke operates in the same fashion as an underground bomb (ideally rendering any fallout as a localized phenomenon), there’s a taboo here that – although we are rightly considering all options – may not be wise to break.
I may be alone in that opinion. The Iranian regime certainly would not hesitate using nuclear weapons on us if it had the opportunity, or Israel for that matter.
Let the national debate commence, but let God help us all if we choose wrongly.
