That's obviously not a good definition, unless you want to include ''all'' armed action. By saying ''usually'' against civilians, violent action against armies is not ruled out as a form of terrorism. For example, by that definition George Washington's fight at Valley Forge would be considered terrorism. I assume that's not what the person who wrote that definition intended.

It's also not a good definition because it seems some terrorist violence is not intended to further political or ideological goals. For instance, were the Aum Shinrikyo sarin gas attacks in the Tokyo subway a form of terrorism, and if so, what political or ideological goal did they support?
