just because the demands are difficult, doesnt mean that the staff will work to make it happen.
The staff can let it fail and place the blame on a rival
The staff can fail, and distract the president
The staff can fail, and blame a convenient political opponent.
The staff can succeed, in a few things, but not the whole remit. They can then spin it as a success
The task could be very complicated and would require multiple steps to achieve it.
But finally, the reason this fails as an argument - is that gutting the security apparatus of the state when you control it, is absurd.
The assumption for this to be non-absurd, is that the CIA is working against the government, and the constitution.
If that was the case, then following the constitution and declassifying their arsenal was not necessary in the least.
Essentially, the theory can be disproved by contradiction/occams razor.
