Tonight's movie is World War III, a 1982 miniseries. I remember seeing it when it came out and thought it was damn good.

From IMDB:
Soviet paratroopers drop into Alaska to sabotage the oil pipeline in retaliation against a United States grain embargo. A skirmish occurs at a pumping station, lightly defended by Col. Jake Caffey and a National Guard reckon unit. A stalemate ensues while the possibility of World War III hangs in the balance. The danger escalates as the Russian leaders and the American President play a cat-and-mouse game.

If anyone needs links, I can provide.
