Internets, yes it can be plural

I know that virtually everyone thinks that Bush used a Bushism when he said internets. Guess what. My dad had a lot of old system manuals for his Industrial Control computers and that is where I first learned about networking. I am pretty sure that there was frequent use of both singular and plural. I found in my first search a definition from 1982 (about right) that uses plural:

1982: INWG establishes the Transmission Control Protocol (TCP) and Internet Protocol (IP), as the protocol suite, commonly known as TCP/IP, for ARPANET. This leads to one of the first definition of an "internet" as a connected set of networks, specifically those using TCP/IP, and "Internet" as connected TCP/IP internets

Yes this is "old school", but so is "Nucular". Nucular is a common pronunciation in the Pentagon.

Geoffrey Nunberg says:

I once asked a weapons specialist at a federal agency about this, and he told me, "Oh, I only say 'nucular' when I'm talking about nukes." In the mouths of those people, "nucular" is a choice, not an inadvertent mistake -- a thinko, not a typo. I'm not sure exactly what they have in mind by it. Maybe it appeals to them to refer to the weapons in what seems like a folksy and familiar way, or maybe it's a question of asserting their authority -- as if to say, "We're the ones with our fingers on the button, and we'll pronounce the word however we damn well please.

I am suggesting that Bush is talking to same kind of people, pentagon types and "old schoolers" and their mannerisms may suit him fine. I bet someone he knows uses the term "Internets".
