The NSA already believes its actions protect national security. It follows its stability protects national interest. Keeping tabs on people who control its budget and accountability keeps it stable.

The only reason I could imagine them not acting on it would be accountability, which almost no one who could hold them accountable is exerting. At least not yet.
