S.H.A.D.E.

S.H.A.D.E. was created as a one-time elite espionage operation by President Lyndon Johnson. Over the decades, it survived in a minimalist form, as a low budget cleanup operation headquartered at the secret Essex Airbase.
The activities of S.H.A.D.E. are unknown until the present day, but what is known is that their budget was repeatedly slashed with the rise of superhumans. However, when all the heroes were occupied with the Infinite Crisis, S.H.A.D.E. became aware of the imminent attack of the Sheeda. When the Sheeda flagship appeared over New York City, they were reinstated as the American government's go-to agency for bizarre goings-on (particularly in light of the news that Checkmate, their predecessor organization, had gone rogue under the leadership of Maxwell Lord).
