(A) the reassignment would seriously jeopardize the national defense interests of the United States;

(B) the frequency proposed for reassignment is uniquely suited to meeting important governmental needs;

(4) Delays in implementation

If the President determines that any action cannot be completed by the delayed effective date recommended by the Secretary pursuant to section 923(e) of this title, or that such an action by such date would result in a frequency being unused as a consequence of the Commission's plan under section 925 of this title, the President may—
