Yes, for the sole reason that it's just a label assigned by an invading enemy government.

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.

Terrorists specifically target civilian or government targets to make a statement or a demand. Those Iraqis were targeting American soldiers. The term doesn't apply here, no matter how badly the occupier wants to impose it on those defending their country.
