They were planned, provisioned, and carried out deliberately on the same day by the same Glenane Gang who were trained, provisioned, and orchestrated by members of the british security forces. That's why they're considered together as The Dublin (and) Monaghan Bombings.
It wasn't just one bomb in dublin btw, it was three car bombs, and the one in Monaghan (about 4 miles from the border) 90 minutes later designed to draw troops and gardai/RUC away from the main Louth/Armagh crossings as the Glenane gang returned to base.
The three separate bombs in dublin aren't known as The Talbot Street, Parnell Street, and South Leinster Street bombings, they're known as part of the group name - Dublin-Monaghan
It was very ironic that you would try to lecture someone else with your "IOTY secured. Omagh was the worse attack by far. Maybe you’re too young to remember but I remember watching the devastation as a 9 year old on tv."
Seems pretty clear that you knew very little of Dublin-Monaghan which you didn't see on tv, but yet presumed to lecture others on what was "the worse attack by far"
