Those threats from the IRA where indeed Terrorist Threats and not Terroristic Threats.
A Terroristic Threat is a threat made for the intent of coercion, influencing specific actions, or instilling fear. There does not need to be any proof that the the threat was supported by means or actual intent to follow through on the threat (at least in my jurisdiction).
Terrorist Threats are made for specific political agenda or change. I don't know much about Terrorist Threats, just that the motives are political.
So the kid who calls a bomb threat in to put off his midterm exam for a few days is making a Terroristic Threat. The guy who threatens to bomb a bridge unless the US pulls out of Iraq is making a Terrorist Threat. And a guy who implies he may go postal for getting released from a contract on unfriendly terms may be making a Terroristic Threat to make those who got rid of him afraid (or he may be making a simple joke that spooked someone, which apparently the police believe is the case after a brief investigation).
