Former NBC News anchor Tom Brokaw returns to primetime with a special report on the war on terrorism on “Dateline” (7 p.m., NBC). Long in the making, this “Dateline” piece took Brokaw to Pakistan, Iran, Saudi Arabia, Afghanistan, France and Washington, D.C., to interview political leaders and intelligence analysts to determine the status of the war on terror, the efforts to capture Osama bin Laden and neutralize Al Qaeda, and to prevent future terror attacks by building bridges to the Muslim world.

Among the notable interviews here is a talk with CIA analyst Phil Mudd, who denies claims that the war on terror has become a “war without end.” He sees a struggle that will “take years and in some cases decades.”

¢ Now here’s something different. “Naturally, Sadie” (7 p.m., Disney) is a live-action comedy about a high school student who is a science geek and proud of it. In a school filled with exhibitionists and artists, Sadie (Charlotte Arnold) craves the soothing certainty of science and the sound foundation of a math equation. Her real desire is to become a famous animal behaviorist like her heroine, Jane Goodall. This makes her all the more qualified to observe the antics of her fellow creatures in the high school zoo.
