You're a retard.
The IRA were fucked after their hilarious failure of a border campaign shit the bed years prior to the Troubles. 
The Troubles-if we say it began when the IRA entered the conflict-happened after Loyalists had been murdering people for months on end.

Even if we go far, far back to the fucking start of the 20th Century, Separatist Irish republicanism only came about because Ulster Loyalists chimped out over Home Rule and literally gave way to extremism within the Irish Nationalist movement.
>muh republicans
Loyalists somehow killed more civilians than the IRA filth during the Troubles and made 0 impact on the IRA's operations.
The history of the Ulster Protestants for the past century has been one of constantly fucking it up, getting their shit kicked in by micks, and having us come and clean it up.

I despise the fact that a single drop of actual british blood was spilled cleaning up after those estate dwelling ulstoid niggers.
