Were the Germans physically superior?

[M. Demetrius]

Wow! That's a very long list of "facts", Abe. Could you provide any documentation to support a few of those?

The Romans defeated most of their foes because of superior tactics, and because they did not seek towards individual glory in battle, but stayed together in their fighting units. Many of the tribal societies they fought(Germanics, Gauls, Britons, et al.) fought to show their "champion" was better than the other tribe's "champion". That didn't do much when the Romans refused to come out of ranks and do individual combat. It had nothing much to do with their "genetic freakism", just training and tactics, and keeping a cool head.

German historians, who were the main writers of the Roman history books that we have known.

I guess, then, Tacitus, Suetonius, Josephus, Polybius were all Germans?
