I'm baffled. One the one hand, the NSA wants their employees to "uphold and defend the constitution". On the other hand, they want their employees to keep secrets.

(... It is possible for these two things to not be in conflict with each other...)

They want their employees to honor the commitments they've made. At the same time they're lying to congress and the FISC.

Dear NSA: Let me help you un-fuck your business: Stop requiring your employees to uphold and defend the constitution. Stop hiring people who believe that the NSA should be held accountable to the citizens and/or to the congress.

(Perhaps you should start by creating a cult of personality around a strong, charismatic leader. And for the signing-in ceremony, instead of swearing to "defend the constitution against all enemies, foreign and domestic", maybe they could just wipe their asses with a copy of the Bill of Rights.)

If you do this, you will never have another Edward Snowden again. I guarantee it.
