"The Unionists instigated the bombing campaign in the sixties?"
Yes
The first bombing in that period was carried out by the U.V.F. led by Gusty Spence at McGurk's pub on May 16 1966
The 'Troubles' where kicked off proper three years later in 1969 when the police directed peaceful Civil rights protesters through mobs of stone throwing Loyalists
Thought everybody knew that.
Perhaps if you cared to read these things up for yourself you wouldn't find what I write "unintelligible"
God knows, there are enough sources
