In WWII the Allies were trying to stop factories in occupied France from producing war material for the German army. They bombed the factory a number of times, but found that it was still producing significant amounts of war material.

To finally reduce factory output to zero they bombed the workers homes near the factory. The thinking was that if you destroyed the worker's housing then they would no longer be able to work at the factory.

The intent was to stop the factory's output. They did that by bombing the workers. This resulted in destroyed homes and civilian deaths. Using your definition this would have been a terrorist attack. I have some difficulty accepting that line of reasoning.
