Speculations by outsiders must give Deep State insiders many opportunities to chuckle, "if only they knew." We don't know, of course, and public leaks are engineered to misdirect our attention from what's actually going on or "frame" our understanding in a positive way.
Decades later, history reveals a very ordinary mix of great successes and horrific failure in secret operations, caused by errors of judgment, faulty intelligence, poor planning and so on. In other words, life isn't tidy, either inside or outside the Deep State.
Nonetheless we can postulate a few things with some certainty. One is that the Deep State-- the unelected, permanent government which includes not just the intelligence community but a vast array of agencies and institutions as well as the top-level structures of diplomacy, finance and geopolitics--is not monolithic.
