Two weeks after the killings, Margaret Thatcher attended another ceremony in Enniskillen.
After even Gadaffi in Lybia had ceased his support for the IRA - and Sinn Fein (the IRA's political wing) later lost a lot of seats/votes.

Quite apart from the Tory £1 billion gift to the DUP - a similar figure is given to Northern Ireland (by the UK Exchequer) to pay its bills. EVERY MONTH!
