Let me put it this way: if Iran has deniably disabled US nuclear capability in the same way that Israel deniably disabled Iranian nuclear capability, the spectrum of options considered by the US government would certainly not end with "send them a strongly worded letter, since we're not totally convinced they did it."
I mean, another country in the neighborhood went for strategic ambiguity for many years. It worked very well right until it didn't.
I certainly don't disagree that it is very dangerous and might cause countries to attack each other in extreme cases. It does give a third party a relatively cheap strategic option to pit countries against each other.
