Considering Israel and the US are bombing Iran’s nuclear facilities because they have “weapons of mass destruction”, if Iran really did have such weapons, wouldn’t bombing the facilities they’re held in cause them to explode, or cause an evident ripple at least? I may be imagining this in a way cartoonier way than military weapons actually work, but I’m preparing myself for some incredibly annoying debates.
And even “precise” would be understating it. Not only is a specific shape of the detonation required, but timing is crucial too. Otherwise you’ll end up with a fizzle.
But yes, the main concern is nuclear contamination in the target area.
