Can I give you a slightly different perspective. It may or may not be right.
Totally Unarmed Struggle=TUS - NOT TUAS!
TUAS is Tactical Use of Armed Struggle
We saw this very clearly in action during the early 90s. Sinn Fein/IRA continued to bomb targets in London and other cities alongside the negotiations that were going on between London and Dublin civil servants. Republicans were involved in the bombing and the discussions simultaneously.
For example, following the tit-for-tat violence in Belfast in late 1993 Martin and Mitchell met Douglas Hurd in Derry on November 5. Douglas may also have met their loyalist counterparts in Antrim later the same day.
Sir Patrick Mayhew announced in the Commons two weeks later that there had been no meetings between Sinn Fein/IRA and Government officials. Douglas of course was a Government minister.
Moloney's misinterpretation of TUAS may have been based on ignorance or connivance. I don't know which.
TUAS is Tactical Use of Armed Struggle
