The problem is that the label is used in media to assign moral judgement, when it's just a political proscription that is typically assigned for entirely geopolitical reasons. Almost every country occupying a foreign territory, or is engaged in war with a group, or even another country, calls military action of the other side terrorism.

It doesn't mean anything. If it is to carry a moral judgement, it needs to be based on universally applied principles. It takes 5 seconds of thinking to see that it's absolutely not based on universally applied principles.
