You can find plenty of references to Hitler and some of his henchmen thinking they're doing the will of god; http://jewsforjesus.org/publications/issues/v16-n10/01

Nor would I describe that as terrorism; the nazi's were the elected party.

Claiming something and believing in something are two different things.

Of course, "tribes" have always painted their fight against the other tribe as God-approved. That doesn't mean that God actually plays a role.

But I was not claiming that; if you take away religion, at least you don't have god on your side. That is what i'm saying.

The word terrorism comes from the Reign of Terror that the French government practiced at the end of the 18th century.
