Is this 'World War IV' serious?

This article by Norman Podhertz is most likely worth our time, judging by what people I trust say.

I first posted on the idea and renaming the "War on Terror" WW IV here, a year plus ago now. There I proposed that WW 4 started, not with the attacks of 9-11, but with the first of radical Muslim terrorist attacks on the West at the Olympics in Munich, Germany, September 5, 1972.

That they attacked and killed 11 Israelis was not necessarily new or an omen for the West. That they killed Israeli Olympian athletes and did this at the Olympics, the western venue for good will and good natured but spirited competions between the respectable nations of the world, is the first manifestation (as far as I can see) of their opposition to the West, indeed the rest of the world.
