The main aim of the Loyalist bombing campaign in the late 1960s was to bring down the Government of Terence O`Neill, the Loyalists knew that even if they hadn`t achieved their aim, the Unionists with their built-in majority were always going to be in power
The Loyalists were determined not to yield an inch, one man one vote would have meant the end of their control in Derry and other Nationalists towns.
As for your belated congratulations of a corrupt RUC they hadn`t much detective work to do as the UVF scored an own goal with a premature bomb blast and the Gardai in Donegal handed over the evidence.

The IRA campaign wasn`t in vain, what more proof do you need than the whinging from the Loyalist of the IRA being rewarded for the successful outcome of their victory.
