Comparison with IRA is false.
The political goal of IRA was unification of the 6 northern counties with the Irish Republic.
That goal could, and can be, achieved by persuading 51% to vote for it.
The Nationalists have now become the majority population in the North.
Soon they will be the majority of voting age.
Then a united Ireland will be achieved.
All the IRA violence achieved nothing but decades of death and poverty.
It did not bring unification one day sooner.

Sinn Fein have achieved considerable electoral success since ending the violence.
They could have done that 30 years ago.
The violent fools.
