Because of our lack of intelligence assets, China and North Korean have done spectacularly well. Pakistan got away with selling nuclear plans for years without our knowledge. There's probably all manner of less complex projects underway that U.S. intelligence is oblivious to.
Like China and North Korea, Iran is something of an outlier. Israel has long had strong intelligence assets in Iran, and in addition to benefiting from those, the U.S. seems to have been able to beef up SIGINT fairly quickly with arguably better than usually results.
It's highly dependent on the technology and the country in question. Sure, at the end of the day it's impossible to keep the genie in the bottle. But the goal is never forever. A country's strategic interests always have an implicit time component. If you can suppress tech long enough for a "rogue" state to become a respectable player in the international system, then you've won. Long enough might be only a few years.
Conversely, if you can develop tech faster than the U.S. can learn about _and_ act upon it, you've won. North Korea won that race, and might have been able to win it even without China protecting it. And how did North Korea win that race? Largely with exogenous skill, importing Soviet talent after the fall of the USSR.
Also, need I remind anyone the intelligence disaster that was both 9/11 and the Iraq War? It's not so much that the intelligence community was wrong, but that there's rarely any certainty in their assessments. If you don't know for certain that something is true, how do you justify your policy decisions? It gets muddy very quickly.
