I chuckled the other day when I heard that the planned attack on the UK airbase used by the US for attacks on Iran, is being blamed on Iran, and also being called terrorism.

I don't think it's terrorism when it's a legitimate military target that takes place during war time. While it is possible for terrorism to exist during a war (you know, something like bombing schools, hospitals, residences, etc), an attack on an enemy's base doesn't fit.
